Hi guys, 

I should make a mesh on a complex and important 3D model. I heared about P-fem method, does it consist in creating of 3D mesh 1st order and then changing that to 2nd order? Could you confirm that it is a better method? 

In fact I saw that when I creat a second order mesh (TETRA or TRIAS), in critical areas, it's possible that there are some elements that have curved edges: is it possible with this method to delete that issue?

 

Thank you

    Yes, when you enter panel 3d>order change> change to 2nd

    set option as 'midside nodes at exact midpoint' => will keep straight element edges
