xxxea proposed the following answer: Hi，Bruno. > I would suggest to use boxes for the walls since they are completely flat. It > would minimize the number of problems for a start. I have tried boxes for the walls and it worked well except boxes can't interact with cylinder, and that's why I use Pfacet for walls. > First problem: triax.wallIds is undefined, so triax engine doesn't know where > to find walls . So I should define a wallIDs list then append Pfacet-wall to it? > Second problem: you can't impose the motion of a PFacet, it always follow the > motion of the nodes. One exception is if you clump facet+nodes into a clump > for each of the walls. Then the clumps' ids should be used to define wallIds. One question, there are 8 nodes and I need to generate 12 Pfacets, so every node would be reused if I clump pfacet+nodes into a clump for each of the walls. Is that workable? Besides, I find only Ig2_GridConnection_PFacet_ScGeom can generate contact between cylinder and other kind of wall-like body, and I have been working on fiber-reinforced sand so cylinder is the kind of body that I must use. Don't really know is there any other body that I can use to simulate wall?
