Turbulent compressible solver rhoTurbFoam with dynamic moving mesh -- CFD Online Discussion Forums

By referring to coldEngineFoam, the modification was pretty straightforward. I named it rhoDyMTrubFoam and successfully compiled it under cygwin/OpenFoam-1.4. To verify the code, I run a cavity problem - but the lid is moving inward sinusoidally (like a piston) rather than sliding. When using paraFoam to view the results, the velocity field makes sense to me. But the pressure and density are constant like they are not properly solved. The run time info shows rho is always zero. what can be the problem?
