I am struggling with a problem in static structural, something similar to this:
\nI already tried increasing the number of substeps (and also the max number of iterations for a single substep) but still it doesn’t solve the problem of moment convergence since after some certain number of substeps, the ‘moment convergence’ graph just keeps on oscillating, with the same mean value. However, as far as the force convergence plot is concerned, it smoothly and easily converges for this region where moment convergence is not found. My model is includes shell and solid, both elements. Now, since the force is already converging, when I access the NR-Residual plots, unfortunately, I cannot see any region within my model which is not finding convergence.
\nTherefore, I need to know how can I determine that region where moment convergence locally is not met? NR-Residuals, as already discussed in this thread, shows where the force convergence is not met. But for moment convergence, I don’t know what to do or where to look, in order to spot those regions where moment convergence criteria is not being met.<\/p>\n
