| Summary | 0003162: Max and Min Functions not working in Cavitation Models for interPhaseChangeFoam | ||||
| Description | In the Schnerr-Sauer cavitation model, the variable mDotAlphal term as defined in SchnerrSauer.C has max and min functions which don't seem to work properly... Cc*limintedAlpha1*pCoeff*max(p-pSat(),p0_), Cv*(1+alphaNuc()-limitedAlpha1)*pCoeff*min(p-pSat(), p0_) I have modified the solver so that it writes out the values for mDotAlphal shown above and the results are not consistent with what is coded. If p - pSat > 0 then mDotAlphal[0] should be non-zero and mDotalphal[1] should be zero. If p - pSat < 0 then mDotAlphal[0] should be zero and mDotAlphal[1] should be non-zero. I have seen cells where both mDotAlphal[1] and mDotAlphal[0] become non-zero. This is not consistent with the way the code is written. | ||||
