The built-in geometry definition and mesher can be used for now for rather simple 2D or extruded 3D geometries. On the other hand, I was not able to succeed with more complicated geometries such as the t4.geo from the gmsh tutorial. Assigning labels effectively works using the solution given in this thread. The library comes with hierarchical high order shape functions so that high order interpolations can be used with an interpolation order adapted to every unknown field and geometrical region. Works for simple geometries (such as example t1.geo), using gmsh-format version 2 ascii (version 4 and INRIA format don’t work). In the latter case the steady-state solution of a time-periodic problem can be obtained in a single step, for linear as well as for general nonlinear problems. The problems can be readily solved in time with a time-stepping resolution or with the natively supported multiharmonic resolution method. Some built-in geometry definition and meshing tools are also provided. Problems with several hundreds of thousands of unknowns in 3D and several millions of unknowns in 2D can be treated on classical laptops. problems (provided in form of a weak formulation ). It can handle a rather general set of problems in 1D, 2D and 3D such as mechanical, acoustic, thermal, electric, magnetic, fluid, electromagnetic, piezoelectric.
