Hi
I am using funkySetFields for initializing a exponential pressure distribution. But when I am running the command "funkySetFields time 0", the domain is getting initialized correctly but the boundary conditions in the 0/p file is getting changed on its own. Can anyone tell why is this happening ? Thanks Anant
