sfepy.fem.projections module

Construct projections between FE spaces.

sfepy.fem.projections.create_mass_matrix(field)[source]

Create scalar mass matrix corresponding to the given field.

Returns:

mtx : csr_matrix

The mass matrix in CSR format.
sfepy.fem.projections.make_h1_projection_data(target, eval_data)[source]

Project scalar data given by a material-like eval_data() function to a scalar target field variable using the H^1 dot product.

sfepy.fem.projections.make_l2_projection(target, source)[source]

Project a scalar source field variable to a scalar target field variable using the L^2 dot product.

sfepy.fem.projections.make_l2_projection_data(target, eval_data)[source]

Project scalar data given by a material-like eval_data() function to a scalar target field variable using the L^2 dot product.
