Unifying shell mesh orientation

Posted by John Moran IV at June 13. 2019

Hello,

I have a quad shell mesh that has been partitioned as seen in the attached picture. My problem is that when I export and convert the .UNV file to CalculiX .INP format, I end up with the shells being oriented differently based on which partition they belonged too. For example, section 1 in the partition might have shell normals facing radially away from the X-axis while section 2 of the partition has normals facing the X-axis. This is causing me all kinds of problems when I apply heat flux in CalculiX because the heating on the surface looks like a checker board.

Is there a way to unify the mesh such that all the adjacent shell elements have a common normal vector? In other words, make them all have a positive face away from the X-axis or towards the X-axis?

Thank you for your time!

John

On a similar note, is there a way in Salome to view shell element normal vectors?
