Thank you Vaclav,
your support helps, as always! For the Frictionless wall, I use the following codes:
wall = woo.utils.wallBox(sp.aabb(),mat=wallMat,which=(1,1,1,1,1,0))
for engines i added :
[Law2_L6Geom_ConcretePhys(yieldSurfType='lin',omegaThreshold = 0.999,epsSoft=ComPlas['Eps_pl'],relKnSoft=ComPlas['K_s']
I still dont understand the difference between wall and facet, is it important to set Density value for wall?
Walls are always global-axes-aligned (see Wall.axis parameter, and Wall.sense) and infinite, whereas facets are triangles (with arbitrary orientation, with active boundary). So use Walls if you can (all computations easier). Density does not matter for Walls, it is used for mass computation, and Walls cannot be integrated as a normal solid (being infinite, inertia being ill-defined). HTH, Vaclav
Now that I tried the second approach, from the force flow it seems to me that the wall did nothing to prevent lateral expansion of my model, at later stage, the particle penetrate the wall and 'flying' away'. I did some inspect and it seem like the engine kinda ignoring them.
Could you help me to make the wall works properly?
Giao, sorry for overlooking this post. Did you manage to make it work in the end? v.
