Greetings,
I tried post-processing for the cavity case using the OpenFOAM 11 utility command "foamPostProcess -func CourantNo" and encountered the following issues: Executing functionObjects --> FOAM Warning: functionObjects::CourantNo - CourantNo cannot locate the required object "phi" of type "surfaceScalarField." --> FOAM Warning: functionObjects::CourantNo - CourantNo failed to execute. I understand that OpenFOAM 11 requires "phi" to run the command, but I'm unable to execute the command similar to 'icoFoam -postProcess -func CourantNo'. I also tried the other foamPostProcess command with the options "foamPostProcess -solver icoFoam -func CourantNo -parallel" but unfortunately, it did not yield the desired results. Any assistance would be greatly appreciated. Thanks, Manikandan Valliappan |

Anybody have any thoughts on this, I have a very similar problem, but with the MachNo postProcess function.
Typically i've run, with previous OF versions, rhoSimpleFoam -postProcess -func MachNo But with v11 it moans, and says, rhoSimpleFoam has been superseded and replaced with foamRun So I run, foamPostProcess -func "MachNo" It runs, but gives the error: functionObjects::MachNo MachNo failed to execute. I've run "foamInfo MachNo" and copied the MachNo file into my system directory from; 1) /opt/openfoam11/etc/caseDicts/postProcessing/fields/MachNo But this does not help. What am I missing? |
