|
In the GUI, interior nodes are defined as a mesh of elements which are flagged as elements in interior of volume.
|
Elements (total, all subregions)

* Solver = stand alone module without graphical user interface, which can be started under Windows command prompt (cmd.exe).
* GUI = graphical user interface. This is the normal mode of use.
