Hey everyone!
I am writing a structured compressible FV code using ghost cells for the boundaries. In order to compute the viscous fluxes, I need to estimate gradient of variables within these ghost cells. In this topic, http://www.cfd-online.com/Forums/mai...vity-flow.html it was suggested that I could set it equal to the gradient in the physical cell to which the ghost cell is attached. Is that how it is typically done? Thank you for your help! Joachim |

Refer code OPENFVM
In the parallel section of the code there is a file gradient.c. A very simple code. I hope you will get information. |
