In many cases you will not know the adequacy of your mesh refinement for your particular solution goal until you have executed a number of analyses and evaluated the solution results. Mesh refinement studies are typically performed in these cases, where a mesh is successively refined and key solution results are confirmed to converge. You can automate this process by applying remeshing rules to regions of interest in your model and using the Abaqus/CAE adaptive remeshing process to automatically perform successive mesh refinement based on a series of executed analyses.
With a remeshing rule you can specify:
The region where you want the mesh refined.
The solution quality criteria (for example error indicators in the Mises stress) that mesh refinement is based on.
The analysis step or steps that refinement is based on.
Minimum and maximum element size constraints.
A sizing algorithm and parameters appropriate to your simulation.
