Hey I have the same problem. I didn't change the surface or core sampling, but the "Sampling control" from the Domain node. It looks like messing with the sampling in any way can cause this. I'm wondering if anyone else has seen this with their Hybrido meshes.

I know what you're talking about Florian. I tried to make an example of it right now but for some reason I can't reproduce it. Basically sometimes when I try to rotate a child object, it seems to shear it instead, and even worse... if I unparent the node after that happens, it's permanently distorte...

In my experience, Shell type volumes cause leaking more than Solid types. Try adding a thickness to your geometry by extruding it a little, then set it to solid inside. This usually works for me. Sometimes changing the solver strictness to 1 helps with leaking as well.

I wanted to try your sim, but I couldn't open the scene because I am using the Learning Edition. I've been watching my k4000 during sims using TechPowerUp (same website). My GPU is not being used at all even though it is OpenCL1.1 compliant. All the work is done on my two 8-core Intel W5590 running...

I have seen this behavior on our new DUAL XEON E5-2680 machines as well. Although not consistently ... I was actually curious if hyperthreading is slowing the machine down ... any thoughts ? On my machine, (Dual Xeon E5-2650) Hyperthreading makes Hybrido 2 simulations significantly slower, and SPH ...

I've done this, it can give you some interesting results. Basically you just need to input the verts from 2 objects with identical topology instead of from 2 displaced plane like the original graph does. The reason you need 2 objects is that the verts from one object will give you the positions for ...

Is your object set to "Active rigid body"? If not then these commands have no effect. Yes its an active rigid. It is falling, when it's position.y goes below 0.0, I apply setVelocity to the vertices or setForce on the object. Neither have any effect for me at the moment. Tried running it as StepsPr...

using:

Code: Select all

for v in obj.getVertices():
	v.setVelocity( Vector.new(0.0,0.0,0.0) )

Has no effect. Am I doing something wrong?

EDIT:

I just tried obj.setForce() and it also has no effect.

Once I hit a few million particles its very slow for me too. If you load it into maya with rfrk, the playblast is much faster for now.

For a mesh object created nside realflow and using inside application, how i create velocity channel? A meshes did'nt have a velocity channel wright?

I think you can use a .md format. I had trouble getting it to work in Maya but I think it can be done.
