chi_mesh.ExtruderMeshGenerator

Extrudes 2D geometry. Extrusion layers are specified using an chi_mesh.ExtrusionLayer specification which takes either pairs of parameters: Pair A = "n" and "z", or Pair B = "n" and "h". When pair A is used then the z-levels will be computed automatically. Vice versa, when pair B is used then the h-levels will be computed automatically. Layers can be specified with a mixture of Pair A and Pair B. For example: Two main layers, one specified using a height, and the other specified using a z-level.

Example usage:

Create this object:

params = 
{
    param_name1 = value1,
    param_name2 = value2,
    --etc.
}
chi_mesh.ExtruderMeshGenerator.Create(params)

Required Input parameters
