Hello FOAMERS, I am running a
 
Hello FOAMERS,
I am running a les-VOF simulation of a liquid jet of 200 bar injected into a chamber. I have been provided with the set up files which were sucessfully used to run such simulations in OF 1.4. But when I use the same set up files to run on OF 1.5. It gave me the following errors:

1. gammaCompression 1.0 , this scheme is not identified and OpenFOAM gave me a list of schemes available to solve the gamma equation, since I could not find the scheme gammaCompression 1.0 in the list, I chose interfaceCompression to solve the gamma equation.

2. Then when i tried to run the solver after this change, it solves the velocity equations for the 0 time step, but while starting to solve the pressure equation it gives me a error message as pated below:

I can see that there is no definition of Pd in the fvSolution file.
But the same setting worked for OF-1.4. so is there any major change in OF-1.5 in solving the pressure equation.

Any comments are welcome
