Adaptive refinement implementation

I know three kinds of adaptive refinement

  1. H-method. Which refine by increasing the number of element and node
  2. P-method. Which increase the order of element polynomial
  3. R-method. This method redistribute the nodes while keeping element number constant

My question is, which one does rfem5 use and how will I implement it in rfem5

RFEM 5 and RFEM 6 use the H-method only for mesh refinement.

This means:
:puzzle_piece: The mesh is refined by subdividing elements, especially in areas with high stress gradients or complex geometry.

Thanks
I don't normally see these refinement in my model after my the adaptive refinement analysis

After my adaptive refinement, my energy error is not distributed uniformly around my wall surface. What is the cause of this because from my study energy error should be uniformly distribute

Could you please post a graphic showing the mesh and the energy error so that I can better understand the problem? It would be helpful if you could also attach the RFEM file. You can also send me the file privately as a private message.
