Hi,
I can not import more than one CAD in new version of LIGGGHT. If I import more than one CAD then it prompts this:

Did you change something in the constructor of the FixWallGranHookeHistory class?
If no, can u send me the script and data needed to run the case?

Hi Ram,

if you want to use 2 meshes you should use the fix wall/gran command as follows:

fix wall/gran .... 2 mesh1 mesh2

Cheers,
Christoph
