mymesh.dmesh

class mymesh.dmesh(raw_NodeCoords, raw_NodeConn, ElemConn, ElemLabels=None)

Bases: StructRefProxy

A specialized mesh class intended for dynamic modification of mesh connectivity.

The dmesh (Dynamic Mesh) class only supports single element type meshes, and only element types that contain a single face type (e.g. wedge elements aren’t supported because they have both quadrilateral and triangular faces).

It’s recommended that a dmesh object is created from a mesh object using mesh.mesh2dmesh(). Incorrect initialization of the mesh will likely lead to misbehavior.

Parameters:

• NodeCoords (np.ndarray(dtype=np.float64)) – Node coordinates array with shape=(n,3)

• NodeConn (np.ndarray) – Node connectivity of elements with shape=(l,m)
