Programming algorithm for coupledPBCNew(). However, matrix returning zeros due to the portion 0 of the global matrix. Undertand how to solve.
Adding checkDiagZero.
Implementing Linalg class with several methods for linear algebra checking. Also, removing methods from MathTools.
Problem of pressure convergence was solved. However, two steps need to be better understood. The imposition of 1.0's in the diagonal of matrix E and method setOnePointPressureBC(). Both are not conducting the code to the same result as they should do.
