Version recovering the validated case for pbc rising on fixed frame. The periodic pressure profile is clean and I concluded, after many tests, that the best combination for bubble simulation is to apply the periodic algorithm to all the matrices: M, Mrho, MLumped, invMLumped, MrhoLumped, invMrhoLumped, GTilde, DTilde, ATilde, ETilde, except for invA. Also, the value of 0.9625 for betaPressure was used, in accordance with the case of beta validation.
Deleting setUnCoupledPBC. Useless method.
Fixing wrong call of method getCentroidVelPos when defining dx.
Fixing periodic algorithm of invMrhoLumped, and invMLumped. The sum of rows/columns should take the contributions inverse of the inverse into account.
Changing wallInvU condition in setGenericBCPBCs() to read only -vel or 0 as condition. This sounds different because there is no mass flow imposed. The periodic pressure shows good curve. However, everything is running well only with pair (GMRES,PCJACOBI).
Eliminating sumIndex for gravity and periodic pressure. This introduces a wrong jump at the extrema because of the copy process.
