Code_aster adaptive meshing

Code_aster adaptive meshing

code_aster integrates an automatic adaptive mesh algorithm based on error estimation. The idea is simple: where the error is important, the mesh is refined; where the error is small, the mesh is coarsened. The mesh is adjusted until the convergence criteria is reached:



Adaptive meshing of a simple 3D geometry. Error estimation is based on the residual. Convergence criteria is the principal stress values.
