fedoo.mesh.generate_nodes

generate_nodes(mesh, N, data, type_gen='straight')

Add regularly espaced nodes to an existing mesh between to existing nodes.

This function serves to generated structured meshes. To create a 2D stuctured mesh:

• Create and mesh with only sigular nodes that will serve to build the edges

• Use the generate_nodes functions to add some nodes to the edge

• Use the structured_mesh_2D from the set of nodes corresponding the egdes to build the final mesh.

Parameters:

• mesh (Mesh) – the existing mesh

• N (int) – Number of generated nodes.

• data (list or tuple) –

  if type_gen == ‘straight’, data should contain the indices of the starting (data[0]) and ending (data[1]). if type_gen == ‘circular’, data should contain the indices

  of the starting (data[0]) and ending (data[1]) nodes and the coordinates of the center of the circle (data[2]). The nodes are generated using a trigonometric rotation.

• type_gen (str in {'straight', 'circular'}) – Type of line generated. The default is ‘straight’.

Returns:

array containing indices of the new generated nodes

Return type:

np.ndarray[int]
