p_rgh in OpenFOAM 1.6
 
Hi all, I'm trying to modify the chtMultiregionFoam solver of OpenFOAM 1.6 adding some of the characteristics of the 1.7.1 version. Apart from the details, I need the 1.6 solver to recognize p_rgh as the new pressure variable for which the solution procedure is performed. I've modified the pEqn.H file in order to reach the goal, but after a seemingly correct compilation when I try to run a test case this is the error message coming out:

FOAM exiting

Any suggestion to fix the problem? Is it possible to redefine the keyword for the pressure variable?

Thank you in advance

PS-Please, do not answer: "Switch to OF-1.7.1 instead of breaking your head on how to modify the 1.6 version...". I know this could be the simplest solution bur unfortunately I must do it the above way....

Maybe it could be more appropriate to shift the post here http://www.cfd-online.com/Forums/ope...tml#post301338

p_rgh in OpenFOAM 1.6
 
I think you must change the name of the p to p_rgh in your code or p_rgh to p in you solution dictionaty. But if I mistake, you can upload your code for more help.
