UDM Access Issue
 

Question related to a previous thread. In my UDF, I set three UDM values for the x y and z components of the face normals on the mesh. After running the executable, I can plot each UDM on the boundaries and they all work and display as expected. Now, when I add a line of code in my UDF calling this UDM and run the executable again, I get a segmentation error. Like I said the UDM is created fine, so I'm not sure why calling it into a new variable would be an issue. I'm also running in parallel, but I'm using the correct RP functions. Any ideas?

Try plotting the values for the UDMs. Secondly, as suggested earlier, try averaging using some dummy number for facecount.
