fix wall/grad

Submitted by Westbrink on Thu, 05/18/2017 - 08:44


when defining the meshes for the fix wall/grad command in the "Physics Models" tab it is only possible to add one single mesh. Due to the fact that I imported several meshes in the "Meshes and Region" tab, I got an error during the simulation.
ERROR: Invalid configuration, mesh Cover should be used for either insertion, wall or massflow measurement

I think this error occurs because the remaining meshes are not called in this command.
I solved the problem easily by adding the other meshes in the input script.

Does the starter version only supports one insertion and one mesh with contact definitions?

Hello Westbrink,
your assumptions are correct, the STARTER version only supports the usage of one mesh as wall. And you are also right - meshes that are imported are not automatically used as walls or anything else and are therefore not permitted by LIGGGHTS if no further definiton is made.
The usage of an unlimited number of meshes with arbitrary many elements is only supported by the PRO version.
