3ds Max :: MassFX Explodes Every Simulation
Oct 30, 2011
No matter what settings I use MassFX seems to explode all of my pieces/particles as if they are under extreme tension just prior to running the simulation.
I have a facade of a bulding broken up into about 1000 pieces. It's real scale and 135' tall. All I want is for the pieces to just fall to the ground. But, no matter what I do at about frame 3 the whole thing just explodes. I've tweaked so many settings that I'm completely lost and can't seem to solve the problem. The default settings are the worst. I've set the 'Damping/Linear' up higher and increased the 'Collision Overlap' but still can't seem to figure what controls this tension or pressure that it appears is in the parts before the simulation starts.

i have some problems combining multiple meshes in one rigid body simulation. What i want to achieve is a button containing a metalplate, a plastic body and a needle 200x multiplied and each of them should be treated as a single massfx object. This bunch should simply fall on a plane ending with accurate, physically correkt positions. My way was using all parts with a physical mesh constrained (RB constraint) to each other part as childs. This works well with one whole button, but copying shows some strange beahviour of the constraints - and doing 200 pieces manually is not the way i want ;-)

I have 3ds Max 2012 and I am trying to do a simulation with mass fx. I am trying to do a simulation where a minecraft character (dynamic object) is walking and then gets hit with a small box (kinematic object) causing him to blow backward into his seperate pieces. My problem i encounter during this is I cant run the simulation unless the parts of the Character are a dynamic body but when i bake the dynamic body it just erases all the keyframes i already had on the minecraft character.

Baked MassFX objects are a headache to animate by hand. I'd like to collapse all the baked animation to regular pos/rot keys. Is that possible?
Right now, I'm cloning objects reseting their position/rotation controllers and linking them to original MassFX objects, just so I could animate pos/rot by hand. I just need a very simple animation before MassFX baked simulation takes place, but the way it currently works makes linking and animation these objects next to impossible.

I'm running Inventor 2008 SP2. Each time I open the assembly 2 subassemblies always explode. You can see the red and blue subs in the attached picture. I thought this was supposed to be fixed by now. Actually I thought this was supposed to be fixed in R11 a long time ago. When I grab and drag either component, everything snaps back to where it's supposed to be.
If this isn't fixed (along with a laundry list of stuff that's been broken since R10) you will be losing customers. This and all the other bugs have cost me countless hours in lost productivity.

IV 2011.
I have an assembly with a FEA simulation result. I can run a report and get the reaction forces and moments at each constraint. I would like to run a new simulation with different constraints and use the reaction results from the first simulation as loads in the second one.
Currently I do this by running a report on the 1st simulation to get a table of the reaction results. I then manually add those forces to the 2nd simulation. This takes time to type and the forces must be edited each time I re-run the 1st simulation.
Is there a way to use parameters to automate this?

One long, thin plane linked at 90 degrees to a rotating cylinder to roll the plane up.Cylinder is kinematic, plane is mCloth with a single strip of verts connected to cylinder which rotates.
MassFX works. Bake all produces keyframes as a masterpoint controller on the mCloth modifier, BUT not as standard max keyframes in the planes transform controller...making it pretty unusable.Sometimes, bake all will end with an "unknown exception". After that, Max transforms are unstable - Moving an object with mouse is unpredictable until a restart.
Repeatable on both Windows XP and Windows 7 - Max 2013 32 and 64
Other features of MASSFX work eg standard rigid bodies etc - seems to relate only to clothOtherwise, any way of rolling up a cloth ribbon that is FIXED at both ends on to a cylinder, I may offer a prize!

I am working on a file (see attached) where I am trying to show a machine spewing out a stream of diamonds. (It is supposed to be a carbon purifier for the air, using nanotech to break the Co2, release oxygen and make diamonds as a waste product) Anyway I can get it to work to the point where i want the diamonds to now pile up on the ground. I have tried to get massFX to make the diamond particles interact with the ground plane but have had no luck so far.
I have tried to put the rigid body on the Super Spray and also on the diamond model?

I get a warning when I open another max scene on another machine here at work, it says:
"The MassFX authored in this file was created with a newer version of the plugins. Forward compatibility is not supported so things might not behave properly."
I am currently using PhysX for Max version: 2.7.1.0202.1800 and PhysX System Software 9.11.0621.
Third party plugins installed for Max being used in the scene are: Rayfire 1.57.10; Orbaz Particle Flow Box #2 ver. 1.07 and #3 ver. 1.53. I've gotten this warning in scenes saved from another PC, opened in another, and not even using any PhysX or PhysX capable plugins.

I'm using MassFx in 2013 64bit. When I apply any rigid body modifier to an object it looks fine but after I save and reload the .max file the scale & position of the rigid body is wrong. This seems random, I've tried switching to CM and Meters etc, nothing seems to fix it.

Tried the "Bake All" option in MassFX?Its seems to make the keyframes on the objects but the "Controller" weights are still set to zero.Which means the baking doesn't do anything. So you have to selection your objects and on both Rotation & Position turn them all to 100.
I just installed 3dsmax 2012 so its a fresh install on windowsXP64bit.
I just made a script to deal with it but if this is how it was released to the public that's pretty crappy.

If you have two balloons falling down on each other, can mCloth interact with the balloons or can the balloons only react to a item like a rigid block?

lately i am often experiencing a problem, where at the opening of scene, a message pops up saying "The 3ds Max file is made of old PhysX plugin. Do you want to convert to current version?" If i click yes, then max freezes, and even after 10 minutes remains frozen, so i have to terminate the process. If i click no, then this annoying message pops up everytime i open my file. I just cannot track down the reference to PhysX plugin in my scene. I can't find it. Is there any efficient way to search & destroy scene connection with PhysX plugin. It's like a plague slowly spreading across my scenes as i merge objects between them.

I'm new to 3ds max, and I was wondering if there was a way to do a spill simulation without a plugin. I've figured out how to do a fluid simulation , tutorial [URL].........
But how do I get the water to stick to the ground. I can't seem to use RealFlow becuase I am on inventor 2013 and that plugin doesn't work for the newer model.

I wonder if there is any plugin/software that makes it possible to do some CFD simulation on my 3dsmax object?
I consider it as an additional part of my current object I'm designing, but I'm no engineer and I've got no possibility to use a real wind tunnel.

What is a good 3rd party application that can produce good fountain simulations? There are a variety of conditions, not just the kind that shoot straight up, but that flow in sheets and synchronize etc.
I have the need for right away and little time to deal with much of a learning curve. I've looked at Real Flow but too expensive, with a complex price scale.

I've created a successful FEA simulation in Inventor 2014 and obtained results. But I want to see the highest stress in a defined area that is smaller than the entire part (I have some stress concentrations that are throwing off my 'max'). Is there a way to probe an area instead of just a point? I'm tired of creating a dozen probes to find the 'local max'.

Fuzor? The features are extremely amazing. I have already tired it for one week due to I am Fuzor's beta tester. The real time simulation are really excellent and I have already tired it for one week. I found that I can't use Revit without Fuzor haha. If you want to know more detail, check the website URL..... It may have more detail and I heard this software “Fuzor” will publish in AU.

What would be the best way to create a wind tunnel model that you can then put different shapes into to see how aerodynamic they are and look at the friction and turbulence?

I'm developing a program which runs several simulations and obtains the results automatically.
I'm using the dynamic simulation API created in Inventor 2013. For that I use the GetResultValues(ByRef values() as Double) method of the class DSResult.
I used the method inside the VBA of inventor and worked well. But when I wrote the program in Visual Basic Express 2010, the method doesn't return anything.
I share an excerpt of the
Dim odoc As AssemblyDocument
odoc=invApp.Documents.Open(testPath, True)
Dim dsman As Inventor.SimulationManager = odoc.ComponentDefinition.SimulationManager
Dim dssim As Inventor.DynamicSimulation = dsman.DynamicSimulations.Item(1)
Dim oJoints As Inventor.DSJoints = dssim.DSJoints
oJoint = oJoints.Item(1)
[code]....
The method GetResultValues(values) should modify 'values' to a time,value vector.
It works well inside Inventor, but doesn't in the program in VB, although it runs the simulations and does everything else right.

when in simulation, if you suppress a feature is it totally taken out of the simulations workings?
I.e. if I was working on a project like some weighing scales and I had a load of objects on the scales and I then suppressed some of the objects, will the scales rise up a little to counteract the reduced weight?

Is this type of gravity experiment possible with dynamic simulation?
[URL].........
I made the cone ramp and double cone but the cone either goes the wrong way or only moves a few inches in the correct direction and then gets stuck. I’m using 3D Contact Joints and Spatial Joints and Gravity Force.

i'm developing a hexapod robot and i want to simulate the motion of the robot's leg. The mechanical of robot's leg contain a servo motor that variate your angle between 0 to 330 degre. How can i delimite the angle of servo's rotation?
Other questions, is about the fixation with bolts. How can i do for the motion simulation respect the connection of the bolt? when i do a dynamical simulation the parts that contain bolts don't stay joints, i have to do a rule of fixation with constrains?

I'm designing multiple elements for a vehicle. I need to evaluate multiple dynamic results of multiple possible designs. All the design is parametric so it modifies quickly but I can't find a way to run the dynamic simulation multiple times automatically and get the results from the output grapher for each simulation.
I am trying to do it via API but can't find the class of the dynamic simulation environment in the Object Model Chart to program it via .NET.
