AMRFEKO is the adaptive mesh refinement utility used to automatically refine the mesh.

The utility calculates the error estimates for the mesh, and based on these estimates, applies mesh refinements. This process is repeated until the error estimates are sufficiently reduced. The last refined model is saved with a new file name. Lower error estimates yield more accurate results. The current implementation is based on error estimates for the FEM.
Tip: Use the FEM solution method when solving a model.
