FLUENT Parallel / sliding mesh
 

Hi,

My simulation is a stirred tank, with sliding meshes. The setup is working fine. I am facing a problem when I save my case and data file in the parallel version of FLUENT 6.2 for windows. When I read back the files into the solver and asks for more iterations, it just stops, draining 100% of the processor, and do nothing. It is a bug in FLUENT or I have to do something else?

Thanks for any help

hi Galeazzo,

I want to know how u modeling the stirred tank.

1)Complete 360 geometry or 180 geometry.

2)How u modeling the interfaces. When you make interfaces fluent creates two wall boundaries? How u modeling them.

i think this may be the problem

Hi Gopal,

My model is a 90 degree slice of the complete domain.

When I create the interfaces in FLUENT, it creates a second wall boundary for each interface. I used the wizard "Grid interfaces" for the interfaces and the command line "grid > modify-zones > make-periodic" for the periodic conditions.

Thanks

Dear Galeazzo

Here everything looks fine. I think the things should work with these conditions.

May i know one more thing. How u seprate the inner and the outer region. R u using Tgrid or Tmerger for it?

Hi Gopal,

I make the inner and outer regions in Gambit at the same time, just use different continuun types.

Thanks
