staggered grid-----------------
 

Hi In fluent which grid scheme is used? If I want to use staggered grid then how I can use it? If any body knows please help me. Mech

Hi,

with Fluent you can't create a grid!!! Just read a grid file. To create your grid, use for example Gambit. And for a staggered grid, I advise you to use size fonctions (there is a chapter dedicated to this part in the Gambit manual).

Hi I use gambit for meshing. In my simulation I need to put field variables like pressure, density etc. at cell center and velocity at face center i.e. I need the scheme of staggered grid. I want to know is there any option in Fluent to set this variable at my desired places or I have to create staggered grid from gambit. If from gambit please refer the section number where I may get the procedure of creating staggered grid. Thank you Fabrice you your suggestion. Thank you all. Mech

Hi Mech,

So to mesh your domain with a staggered grid and the use of size functions, have a look at the section 5.2 of Gambit manual.

To set your variables, you need to define an UDF, I think (but not sure...) with the macro DEFINE_ADJUST (section 4.2.1 of UDF manual).

Regards,

Fabrice.
