Attributes and Installation
Netgen is a tetrahedral mesh generator and editor. It is available either as a Windows executable or as a tar file, so UNIX/LINUX users will need to compile it from source. It can be installed on Ubuntu systems with
dnf install netgen-mesher* and launched with
netgen-mesher in a Terminal window.
Netgen can read in CSG or BRep Geometries and generate corresponding tetrahedral meshes. It can also read IGES and STEP formats when compiled with Open Cascade.
