Creating and meshing a simple 3D model

We start from scratch and create a simple 2D geometry interactively, by defining points, lines and surfaces. We then extrude the surfaces to create the final 3D model. As the geometry is constructed, commands are automatically added in the untitled.geo file; the resulting file is available here.

Post-processing scalar and vector datasets

We reuse the model created above, where we added two physical groups so that the mesh can be used with the GetDP solver. We also added a few parameters; the resulting model is renamed elastic.geo and is available here. We then run a linear elastic solver elastic.pro to compute displacement modes of the structure, and we perform some post-processing operations interactively. The GetDP solver file is available here.
