[Libmesh-users] Characteristic-based Split Algorithm

2014-07-10 Thread Sahai, Amal
I am attempting to build a unsteady compressible Navier Stokes solver using Libmesh. I was planning to implement the characteristic-based split algorithm described in Volume 3 of Finite Element Methods (Zienkwicz). The algorithm essentially comprises of the following steps: 1) Compute momentum
