Hi,
I am a newbie to OpenFoam. I ran a laminar simulation of the flow around a sphere and I want to compute the wall shear stress and skin friction on the surface of the sphere. When I type postProcess -func wallShearStress -time latestTime I get this error message: --> FOAM FATAL ERROR: Unable to find turbulence model in the database From function virtual bool Foam::functionObjects::wallShearStress::execute() in file wallShearStress/wallShearStress.C at line 200. From what I read the wallshearstress includes the turbulent shear stresses which in my case don't exist. How can I compute the wall shear stress on a laminar simulation ran with icoFoam? |

Hi,
If you check the options for icoFoam you will see that there is no "postProcess" available icoFoam: Code:
Usage: icoFoam [OPTIONS] options: -case <dir> specify alternate case directory, default is the cwd -fileHandler <handler> override the fileHandler -hostRoots <(((host1 dir1) .. (hostN dirN))> slave root directories (per host) for distributed running -libs <(lib1 .. libN)> pre-load libraries -listFunctionObjects List functionObjects -listScalarBCs List scalar field boundary conditions (fvPatchField<scalar>) -listSwitches List all available debug, info and optimisation switches -listVectorBCs List vector field boundary conditions (fvPatchField<vector>) -noFunctionObjects do not execute functionObjects -parallel run in parallel -roots <(dir1 .. dirN)> slave root directories for distributed running -srcDoc display source code in browser -doc display application documentation in browser -help print the usage Code:

Hi there!
I'm having the same problem when I submit the next comand: Quote:
Then it jumps the same error you mentioned. Could you explain how did you obtain the solution for that case? I'm using simpleFoam instead, and runing a laminar flow case. Thanks! |
