Particle moving through .stl-walls

Submitted by RobertG on Fri, 10/31/2014 - 12:33

Hello again,
I'm working with a program, based on the tutorial Continuous Blending Mixer.
My Problem is, that at the insertion area, the particle start to "explode" at a certain time.
That means, some of the particles are going through the wall of the .stl-file.
The starting velocity of the particles is high enough to avoid, that some of the old ones are still in the area, when the new ones are created.
I'm shure, that the area they are created is not too small and there is plenty of space between the the area they are created and the wall.

I hope some one can help me.

Best regards
RobertG.

Hi Robert,

that can be many reasons: timestep too large, Youngs Modulus too low, particles which are inserted instantaniously overlap a wall (just to name a few)

Hi Christoph,
thanks, it was the timestep. I reduced the insert velocity and it worked.
Thanks a lot.
