Hi,

I get the following error report when running sHM on a simple prism. I made the .stl file myself with Rhino 5.0.

I do not understand why I get two zones, volume and volume (see further down)????

Hi, I dleted everything except the essential files and then the problem went away. Now I have to figure out how to use it...

I am now struggling with naming surfaces in a .stl file and then assign mesh levels and boundary layers.
