Adaptive mesh refinement
With this function, it is possible to refine the FE mesh on surfaces automatically. The mesh refinement is gradual. In each step, the FE mesh is recreated based on an error comparison of the results in the previous calculation step. The numerical error is evaluated from the results of surface elements and is based on the energy formulation of Zienkiewicz-Zhu.
The error evaluation is carried out for a linear structural analysis. A load case (or load combination) is selected and the FE mesh is created for it. This FE mesh is then used for all calculations.
