i use ansys fluent 13 and i faced this error:

Error: Cannot allocate memory for facets during surface creation

i hope founding solution

Hello,

my first estimation is that there is problem with low RAM in your PC. When does the error appear? During meshing in Mesh application? If yes then probablly RAM is getting filled - you model has a big size and a lot of cells then.

Also i think you need a system with higher ram. what's your model dimention? How many grid it has?

many thanks i solve the problem by decrease number of iteration

If the similar message appears when I trying to display the velocity vector does it also mean the RAM is filled?

I guess yes. In the case where ploting of vectors takes long time (because of large 3D model - many cells) I think the system uses RAM somehow for this ploting.
