Hello everyone!
I found problem with mesh refinement- It works only if value of mesh refirement is between max and minimum element size, set in Meshing parameters. If i try to use other value, I can see on previev that program shows theoretical nodes, but during mesh generation sizes of the elments are the same as during meshing without any refirements. Problem is in PrePoMax 1.2, and I also saw this behaviour in 1.1.1 (I’m not sure, but in earlier version problably I haven’t found that issue.
That is true. The program that meshes the geometry is Netgen and it supports global and local settings where local settings can only be between the globally defined max in min values. This can not be changed. The red “highlight” representation of the mesh refinement when selected in the geometry tree on the other hand uses PrePoMax computed node positions and does not account for the global settings.
I do not want to complicate things too much by checking the values of the mesh refinement size vs the global mesh sizes since one or the other can be changed by the user and push the other out of the limit. So I will add a description to the value of the mesh refinement size that only values between min and max are useful and I will fix the highlight of the mesh refinement to account for the global mesh limits.
Any other ideas?
Netgen behavior is the same as observed in some commercial FEA programs, for example SOLIDWORKS Simulation. I think addition of a description you mentioned will be enough for the most users.
Thank you for this information.
I tried also a mesh refiremnt, with higher values on edges, which were not important for me, with global parameters(min-max with values I preffered for caluculation on the point of interest) but now I can see that it was a wrong solution too 
The mesh refinement highlight bug was fixed. An explanation was added to the Element size entry of the mesh refinement.
