quality of the mesh #20

Hi Dorian,

Do you have any recommendations on the acceptable mesh quality for Prism-plasticity. Any rule of thumb on the "threshold" values of SICN, Gamma, and SIGE? How good is good enough?

Many thanks,

Diego

Hello Diego, Unfortunately I have no recommandation about threshold values, and I know it is pain to get an acceptable mesh for PRISMS-Plasticity. This is because we use HexOnly, resulting in some highly distorted element (usually near triple junctions). Here is the quality values I get on mesh I use in PRISMS-Plasticity (and it works): image

If you really do not manage to get a proper mesh, avoid the gradient option.

Thanks Dorian!

Avoiding gradient option works!
