Hi,

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.

Hi,

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.
