OF 2.x, cyclic boundary and MRFSimpleFoam compatibility
 
Hello dear forum

Did anybody experiment OF 2.1.0 with cyclicAMI boundaries and MRFSimpleFoam ? Is it supposed to work ?

I used to do that with OF 1.5-dev. I'm testing OF 2.1.0, from RPM packages for SUSE.

I get following error :

Code:

Exception en point flottant
Does anybody have a suggestion ?

Thanks in advance, and best wishes

PS : many thanks and congratulations to OF maintainers team for the last evolutions of the software : AMI, edges in SHM, packaging

I configured a cyclicAMI case last weekend (using rotationally cyclic boundary conditions), and it seemed to work smoothly. Granted, I'm having convergence issues with MRFSimpleFoam, but I'm fairly certain it's a setup issue and has nothing to do with the AMI implementation (It's looking like the boundary patches need to be further offset from the rotating features).

Can you provide more detail on your case? Perhaps post the case files if they aren't too big?

[SOLVED] cyclicAMI + MRFSimpleFoam crash
 
Hi Mickael


Thanks for your attention. Finally I found the fix on the forum. Running following command did the job :

Code:
unset FOAM_SIGFPE
Don't ask me why

This forum is very good. Thanks to everybody

It doesen't work...just there was not the warning ,but can't calculate.

I think it's because you over estimate the boundary values of k and epsilon

plz tell me it is true???or not???
 
hi Dear Foamers.
I want to add k(kinetic turbulence energy) in one solver.

for this reason added this line in code :

const volScalarField &k=U_.db().lookupObject<volScalarField>("k")
and wmake was Successfully .

but How can I Understand that this k is the same with k(kinetic turbulence energy)???Is it true?????

Because I replase another world in this :

const volScalarField &M=U_.db().lookupObject<volScalarField>("M")
but not error occured!!!!!!??????
