- adi_3d_indexing()#
Solve a PDE in 3D domain using ADI method. Use provided slices to solve for certain regions.
- Parameters:
d – right hand side vector
x – vector to be solved
s1 – index triples for x-axis, that define a 1d slice
s2 – index triples for y-axis, that define a 1d slice
s3 – index triples for z-axis, that define a 1d slice
a – equation coefficient, proportional to diffusivity
boundaries – type of boundary conditions: 0 for 0 at boundaries, 1 for fixed boundaries, 2 for no flow through boundaries
