drag an lift coeffis after solution is done using ExecFlowFuntionObjects
I would like to calculate drag an lift coefficients after solution is done, It is possible to calculate it using “execFlowFuntionObjects” it generate a folder for forces and for forceCeffs, but it overwrite the file for every time-step.
When I solve the case the controldic works well, but it is no possible to use the same dic for postproccesing. My controldic is: functions { forces { type forces; functionObjectLibs ("libforces.so"); //Lib to load patches (name); // change to your patch name rhoName rhoInf; rhoInf 1.225; //Reference density for fluid CofR (5.885 0 0); //Origin for moment calculations outputControl timeStep; outputInterval 1; } forceCoeffs { type forceCoeffs; functionObjectLibs ("libforces.so"); patches (name); rhoName rhoInf; rhoInf 1.225; CofR (5.885 0 0); liftDir (0 0 1); dragDir (-1 0 0); pitchAxis (0 1 0); magUInf -20; lRef 5.885; Aref 8.91037; //projected area outputControl timeStep; outputInterval 1; } } Can someone help me?

Hi angel,
Are you doing a transient simulation? I'd like to do the same for a transient simulation - I have a bunch of results for which I've now decided I'd like lift and drag coefficients for. Does anyone know how to do this?? I had no idea about execFlowFunctionObjects - what does this do? |
Any solution for this problem? Why is the forces file overwritten each time step for postprocessing with execFlowFunctionObjects?
