fix rigid and its limitation

Submitted by NielsD on Wed, 02/06/2013 - 10:22

Hello

I have a problem regarding the movement of particles clumped together with the help of "fix rigid".

My simulation consists of a vibrating plane (stl-mesh). The clumps are on the top of this plane.
If I simulate the clumps, the moving behaviour is not like it should be.
My clumps look like cubes and consist for example of 3x3x3 particles of the same size without any overlaps.
The simulation works well for single spherical particles or for clumps with 10x10x1 (like a disk flat on the top of the plane).

Is it possible that the damping for the fix rigid is not calculated correctly? Or could anybody say if there is another problem in the fix rigid which i should have in mind.

Thanks in advance and kind regards

Niels

Hi Niels,

>>Is it possible that the damping for the fix rigid is not calculated correctly?
that should be correct

>>If I simulate the clumps, the moving behaviour is not like it should be.
what exactly do you think is not correct?

Cheers,

Hi Christoph
i try to run some more simulations to see what the problem is.
If I have further informations i contribute these to the forum.

Cheers Niels
