Default ANSYS CFX meshing bed of particles
Tim Donohue
Posts: n/a

I have a simulated bed of spherical particles that are drawn in vrml 2.0, which I convert to an iges file through Solidworks. I can then import the iges file into the ANSYS geometry modeller making sure to simplify topology and geometry. I then extrude a cylinder to enclose the particles and use create>body operation>cut material to remove the particles. When I try and mesh this geometry though I get errors. The most common ones are;- *the volume mesher cannot continue. it is contiually adding and removing the same elements *No boundary edge found

I am not very experienced with this software so I am unsure of how to deal with these problems. Any help or advice would be appreciated. Tim.

Generally this is caused by the mesher trying to put too large elements in a small gap. Check that you mesh is fine enough to resolve the geometry.
