Problems with Unsteady simulations using LRR Model in transientSimpleFoam
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

FOAM aborting

Can anyone tell me what the problem is??

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

A slight modification yields the results!!!
