This utility computes the average cell volume of the computational grid, which can be used to estimate the GCI metrics such as average representative grid size.

How to compile the code?

Make sure that OpenFOAM is sourced on your current terminal session

1. Copy the code base to the location

OpenFOAM/username-ofversion/applications/utilities/getCellVolume

2. Enter the getCellVolume directory and compile

wmake
