MeshSolver

class compas_shapeop.meshsolver.MeshSolver(mesh)

Bases: Solver

Create a solver from a COMPAS mesh.

This is a convenience method that allows you to initialize a solver directly from a COMPAS mesh.

Attributes:

meshcompas.datastructures.Mesh

A COMPAS mesh.

pointsnumpy.ndarray

Direct reference to the solver’s points matrix in shape (n, 3).
