InterDyMFoam with GGI
 
2 Attachment(s)
Hi Foamers,

I am trying to simulate a case with two fluids with a moving mehs. First i have looked at the interDyMFoam tutorials but these cases doesnīt fit to my Problem.

I take the tutorial case mixerGgi from icoDyMFoam and modify it for a simulation of 2 fluids. The Problem is that the Case doesnīt run.
So I modified the interDyMFoam Solver and delete everything that I get only the moving. This works fine.

But when I use the normal interDyMFoam solver i got a "Floiting point exception" and i donīt know where the Problem is.

Thank you for your Help

Sebastian

Hi Sebastian,

I had a look at your case and the reason for floating point exception is caused by the initial boundary conditions for k and epsilon.

On the ggi patch I changed their uniform value to sth. different than 0 and added entries for k and epsilon to fvSchemes and fvSolution. Case is running now, see attached file.

Best,
Andreas
