Nonlinear Adaptive Region is applied on the Billet body using Mesh Criterion with Maximum Corner Angle of 160 degree and Specified Recurrence Rate 1 for the Entire Load Step as illustrated below. This setting monitors the corner angles in all of the elements on the billet body at the end of each converged substep and triggers remeshing when the angle exceeds 160 degrees.
The Analysis is solved using Step Controls with Initial Substeps = 20, Minimum Substeps = 10 and Maximum Substeps = 2000, Large Deflection set to on, Stabilization Nonlinear Control set to off, and the Nonlinear Adaptivity Remeshing Controls as listed below.
Here the remeshed region will retain the sizing gradient of the original mesh with additional sizing compensation based on the element size change due to deformation during solution. The boundary angle threshold is set at 10 degrees and 10 layers of elements are used from the distorted element to create the new mesh.
