ShellSolver calculation of stress strain

Post by philnik »

While solving problems with 2D meshing on 3d structures with ShellSolver,

I get results of U and DNU.

Is there any option or example how to get also von misses / tresca like on Elasticity models.

Use the flags in the solver section

Calculate Stresses = True
Calculate Strains = True

These commands work in the case of 3-D models, but strain/stress computation has not yet been implemented into the solver module ShellSolver. The old facet shell solver module FacetShellSolve (which is undocumented and whose use in shell analysis may require caution as a simple combination of a plane membrane element and a plate bending element is used) seems to support the keyword "Calculate Stresses".

The implementation of strain and stress computation into the module ShellSolver has been a to-do task.
