Problems with Unsteady simulations using LRR Model in transientSimpleFoam

barath.ezhilan · July 24, 2009, 06:51

Hi All,

I am trying to run Unsteady simulations using LRR model. I have followed the steps mentioned by Jasak here
(This was for SimpleFoam)
ie) Running k-epsilon for the first 100 iterations, calculate reynolds stress using R function and changing it to LRR

I am getting the following error

Create time

Create mesh for time = 0.0175

Reading field p

Reading field U

profile1DRawData:: Reading file : "/mnt/fs2/home/ebarath/project/jgrupp/SST_GAMG/unsteady/LRR/Netz9_improvement/constant/messein_Drall30_OF.csv" in turboCSV format
Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Selecting RAS turbulence model LRR

interpolateCoord not recognized: ""

From function profile1DfixedValueFvPatchField<Type>:

rofile1Dfi xedValueFvPatchField(const fvPatch& p, const DimensionedField<Type, volMesh>& iF, const dictionary& dict)
in file finiteVolume/fields/fvPatchFields/derived/profile1DfixedValue/profile1DfixedValueFvPatchField.C at line 189.

FOAM aborting

Can anyone tell me what the problem is??

The problem was actually with the R file generated for the last k-e timestep!

A slight modification yields the results!!!
