Hi Clemens, thanks for the advice.
I supposed that point supports is not the best way for the stress singularities but I don’t think in this massive way.
The problem is that I cannot even choose a shear value and supposing it’s almost right, because there’s the same problem of higher value for high discretization mesh.
I will try with these short beam peaces and support some point along of them, but in this way I have to include these in the mesh and I cannot use the regular mesh, but the inclusion brep.
If, after this I have the same problem, what can I do to have a shear stress value in x and y? I can’t choose 3000 kN/m value because it’s not true as stress value for a model like this.
I just need an approximate value to impose verification on shell element.
Best,
Leonardo
