Space-time block preconditioning for incompressible flow

Federico Danieli, Ben S. Southworth, Andrew J. Wathen

Parallel-in-time methods have become increasingly popular in the simulation of time-dependent numerical PDEs, allowing for the efficient use of additional MPI processes when spatia…

A constrained pressure-temperature residual (CPTR) method for non-isothermal multiphase flow in porous media

Thomas Roy, Tom B Jönsthövel, Christopher Lemon +1

For both isothermal and thermal petroleum reservoir simulation, the Constrained Pressure Residual (CPR) method is the industry-standard preconditioner. This method is a two-stage p…
