coarsen_operator_k

• Inherits from: coarsen_operator_base
• Defined in: src/IJK/Multigrille/Coarsen_Operator_K.cpp

Coarsening operator based on z-coordinates read from a file, in IJK discretization.

Parameters:

• file_z_coord (type: string) Name of the file containing the z-coordinates defining the coarse grid.

coarsen_operator_uniform

• Inherits from: coarsen_operator_base
• Defined in: src/IJK/Multigrille/Coarsen_Operator_Uniform.cpp

Object defining the uniform coarsening process of the given grid in IJK discretization.

Parameters:

• [coarsen_i] (type: int) Coarsening factor in the I direction (number by which the cell count is divided to build the coarse grid).
• [coarsen_j] (type: int) Coarsening factor in the J direction.
• [coarsen_k] (type: int) Coarsening factor in the K direction.
