In order to define node mesh refinements, further options for the FE length arrangement have been added in the new program versions. You can now define a radial, a gradual, or a combined FE length arrangement.
In the case of a radial FE length arrangement, the refinement area expands uniformly from the inside to the outside. With a gradual FE length arrangement, the refinement takes place section by section in areas with the same mesh size; with a combined FE length arrangement, the distribution results from a combination of radial and gradual adjustment.
