- | To load complex data | + | To create more complex meshes one can use also tetrahedral mesh, which can be obtained (with one intermediate step) from 3D modeling software, like [[http://www.blender.org|Blender]]. Software tools for 3D modeling usually do not provide mesh itself, however they can save some files, e.g. in STL format that can be directly used for mesh generation. Then, a mesh generating software is used, like [[http://wias-berlin.de/software/tetgen/|Tetgen]]. This outputs .node and .ele files that GSvit can read. |
