adi_3d()#

Solve a PDE in 3D uniform domain using ADI method with backward Euler scheme.

Parameters:

  • d – right hand side vector

  • x – vector to be solved

  • a – equation coefficient

  • boundaries – type of boundary conditions: 0 for 0 at boundaries, 1 for fixed boundaries, 2 for no flow through boundaries
