GCL (Geometry Conservation Law) or SCL

researcher · August 8, 2015, 11:39

Could anyone please clarify to me how addition of GCL equation affects solution complexity ?
Does it make the system of equations overdetermined ?
How the complication increases especially if one is using Roe FDS method for inviscid flux and additionally a limiter also ?

Thanks in anticipation.

Hello everybody
Can someone pls tell me if we are solving a movi g mesh problem explicitly, do we still need GCL ? Since we know the volume and velocity of the mesh before and after, why would we need GCL ?
