It seems that mpheval evaluates data with a density far scarcer than that of the actual FEA mesh. How to control the density on which mpheval evaluates? Same question for mphinterp.

Hi Carl

For mphinterp you have to specify the coordinates yourself.

Mpheval uses the same nodes as your mesh by default. If you have higher order elements you may want to use the refine argument.

Thanks Dr Gregersen. But somehow I found, mpheval uses NOT the same nodes as my mesh, but a far coarser mesh.
