Hi all,

I am writing because I have tried everything and the moment to ask for help has arrived.

I am trying to obtain Cd and Cl drag and lift coefficients of an already run simulation using the wonderful capability of postProcessing.

when I use the following:

pimpleFoam -postProcess -func forceCoeffsIncompressible

I obtain:

nProcs : 1
sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster
allowSystemOperations : Allowing user-supplied system call operations

Create time

Create mesh for time = 0


PIMPLE: Operating solver in PISO mode

Selecting incompressible transport model Newtonian
Selecting turbulence model type laminar
No MRF models present

When I don't have any 'patch1' nor 'patch2' ...
I have tried to run it with the function included in the controlDict and it worked fine but the problem is that the simulation took weeks to get here so I can't rerun it again.

Please if any can take a look to the case I attach in the message the case folder. It only needs to:

bash ./AllMesh
pimpleFoam

This is OF4. Please run some timesteps and when you already have several time folders try to get the forceCoeffs from the written folders with postProcess.


Thanks a lot in advance
