mesh.Mesh.points_at

Mesh.points_at(rst)

Compute points at parametric values.

Parameters

rst: array_like

A float array with shape (ndim, npts) specifying the parameter values for the point to be computed.

Returns

coords: Coords

A Coords array of shape (n_elems, npts, 3) with npts points at parametric values rst for each element.

Examples

>>> M = Mesh(eltype='quad4').subdivide(2,1)
>>> pts = M.points_at([[0.5, 0.2],[0.5, 0.2]])
>>> print(pts)
[[[0.25 0.5  0.  ]
  [0.1  0.2  0.  ]]

 [[0.75 0.5  0.  ]
  [0.6  0.2  0.  ]]]
