Eng.Mahmoud abd elsalam is on a distinguished road
hi , every one
iam working on the compressor cascade and i want to make a validation with paper but, i faced a big problem to make periodic BC in fluent , errors usually appeared.
i tried to overcome this periodic problem with setting zone with symmetry BC
but, the results of contours not matched with validation paper
this is 2d mesh of my project

any periodic BC replaced by symmetry BC
and this is what i should do

any one can help me
thanks advanced
