fedoo.Mesh.convert_data

Mesh.convert_data(data: ndarray, convert_from: str | None = None, convert_to: str = 'GaussPoint', n_elm_gp: int | None = None, method: str | None = None) → ndarray

Convert a field between node, element and Gauss-point storage.

Parameters:

  • data (ndarray) – Field values. The last axis stores the points.

  • convert_from ({'Node', 'Element', 'GaussPoint'}) – Source and target storage. If convert_from is None, it is inferred from the last axis length.

  • convert_to ({'Node', 'Element', 'GaussPoint'}) – Source and target storage. If convert_from is None, it is inferred from the last axis length.

  • n_elm_gp (int, optional) – Number of Gauss points per element.

  • method ({'mean', 'l2', 'spr'}, optional) – Method used when converting Gauss-point values to nodes. 'mean' keeps the historical element-wise extrapolation followed by nodal averaging. 'l2' performs a global L2 projection using fedoo’s node-to-Gauss-point interpolation and quadrature matrices. 'spr' performs a linear Superconvergent Patch Recovery around each node.
