OptiStruct – Thickness change output for Large Displacement Nonlinear Analysis
Product Version: OptiStruct 2019.0 or above
Thickness change output for large displacement nonlinear analysis with OptiStruct.
THICKNESS output has always been available for size or free-size optimization for shells and composites.It is now supported for shell elements in LGDISP analysis (NLSTAT & NLTRANS).It is very useful to visualize how much the ‘thickness’ of the shells are decreasing or increasing (specially in necking type applications).
