I want to develop model of a a cube with sand particles (Spheres) inside. I want to analyze it in ANSYS. Spheres are randomly generated in Matlab as shown in the Figure. I want to export the geometry to ANSYS and mesh it.

ANSYS is CAD Neutral. Write it out in one of the formats such as para solid etc. and import it back into Design Modeler or SpaceClaim.

Help

Here is a matlab script that exports IGES files, which you could open directly using SpaceClaim.

Since you have some programming skills aoub07, you can learn the scripting language of SpaceClaim and have the script read a simple text file of the x, y, z, r values of the center and radius of the spheres, then have the SpaceClaim script create the spheres.

I have the coordinates of each sphere (x,y,z,r) and I want to know how to gener the geometry.

I'm sure I answered this question a few days ago: there are journal features in SpaceClaim that'll help with this. Note, you'll need to make sure the spheres don't touch otherwise the mesh count will most likely be too high to solve on the Student software.

I created the geometry in Spaceclaim. Thank you all.

Hey aub07

Is it possible to make that packing in a cylindrical container ?

I made a packing in blender (exported as .stl file) but is giving me errors during meshing

Could you help me out here ?

I have the same problem. I imported the file from MATLAB using space claim but I couldn't mesh the generated geometry. Could u plz help me in doing that.
