I recall that, when using a VtkExport engine in a Yade simulation that contained a mesh, the engine would export the force values (as well as stress values) for each facet in the mesh. This does not appear to happen when I do the same thing using a VtkExport in Woo. Is there a workaround for this? Is there any way to use ParaView to view the total magnitude of force on each facet in a mesh?
On a related topic, I am currently calculating the total force on a mesh by adding up the force values for all contacts for which either id1 or id2 matches the id of a particle somewhere in the mesh. Is this an accurate method of calculation?
Cheers and appreciate the help,
force on triangulation is currently not saved. How would you like to add it? Summing up forces is the correct approach, now do we want to have nodal forces (which might be reaction from the mesh) added as well? Only forces which are normal to the facet, or all of them? And do we divide the force by facet area, so that we have (mesh-size independent) something with stress dimension? Once we clear this out, it can be added to VtkExport in no time.
Would you perhaps open a new issue at https://github.com/eudoxos/woodem/issues to track it?
When you sum forces by hand, a few points
