- CylindricalMesh.get_interpolation_matrix(loc, location_type='cell_centers', zeros_outside=False, **kwargs)#
Construct interpolation matrix from mesh.
This method allows the user to construct a sparse linear-interpolation matrix which interpolates discrete quantities from mesh centers, nodes, edges or faces to an arbitrary set of locations in 3D space. Locations are defined in cylindrical coordinates; i.e. \((r, \phi, z)\).
Location of points to interpolate to in cylindrical coordinates ; i.e. \((r, \phi, z)\)
What discrete quantity on the mesh you are interpolating from. Options are:
‘Ex’, ‘edges_x’ -> x-component of field defined on x edges
‘Ey’, ‘edges_y’ -> y-component of field defined on y edges
‘Ez’, ‘edges_z’ -> z-component of field defined on z edges
‘Fx’, ‘faces_x’ -> x-component of field defined on x faces
‘Fy’, ‘faces_y’ -> y-component of field defined on y faces
‘Fz’, ‘faces_z’ -> z-component of field defined on z faces
‘N’, ‘nodes’ -> scalar field defined on nodes
‘CC’, ‘cell_centers’ -> scalar field defined on cell centers
‘CCVx’, ‘cell_centers_x’ -> x-component of vector field defined on cell centers
‘CCVy’, ‘cell_centers_y’ -> y-component of vector field defined on cell centers
‘CCVz’, ‘cell_centers_z’ -> z-component of vector field defined on cell centers
If False , nearest neighbour is used to compute the value for locations outside the mesh. If True , values outside the mesh will be equal to zero.
