See tutorials/compressible/rhoPimpleFoam/RAS/squareBendLiq for exapmle pimpleControl: Added SIMPLErho option for running in SIMPLE mode with large time-step/Courant number and relaxation. With this option the density is updated from thermodynamics rather than continuity after the pressure equation which is better behaved if pressure is relaxed and/or solved to a loose relative tolerance. The need for this option is demonstrated in the tutorials/compressible/rhoPimpleFoam/RAS/angledDuct tutorial which is unstable without the option.
