autopdex.seeder.int_pts_in_line_mesh(x_nodes, elem, order)

Given a mesh of lines, it linearly maps integration points from a reference line onto the actual lines

Parameters:

• x_nodes – nodal coordinates of all nodes of the mesh

• elem – nodal indices of each line element (if an element has more than 2 nodes, the first 2 nodes are used for the mapping)

• order – polynomial accuracy order of integration rule within each line

Returns (coor, connectivity, weights):

• coordinates of integration points

• connectivity of integration points, i.e. list of all nodes that have a contribution

• weights of integration points
