Mesh Solver

Geometry

The mesh solver operates on an unstructured mesh specified in the MSH format. Neper and Gmsh are the recommended tools to generate mesh solver geometries.

Load Case

The load case of the mesh solver is written in YAML style. It contains one top-level key:

• loadstep

loadstep

… is a list of dictionaries that specifies the details of each individual load step in the simulation. Every load step has a number of parameters that need to be declared:

• discretization

  • N: number of increments

  • t: time of load step in seconds, i.e. \(t = \sum_{i=1}^N \Delta t_i\)

• f_out: output frequency of results; e.g. \(f_\text{out} = 3\) writes results every third increment

• boundary_conditions

  • mechanical

    • dot_u: t.b.d.

    • tag: t.b.d.
