inline virtual Field3D solve(const Field3D &b) override#
virtual Field3D solve(const Field3D &b_in, const Field3D &x0) override#

Performs the laplacian inversion y-slice by y-slice

Parameters:

  • b – [in] All the y-slices of b_slice, which is the right hand side of the equation A*x_slice = b_slice

  • x0 – [in] All the y-slices of the variable eventually used to set BC

Returns:

x All the y-slices of x_slice in the equation A*x_slice = b_slice
