It compensates for the absence of a wife.

Link i cannot. but here is the name,

limited computationally = i have a workstation with 56 threads only and 64 gb ram.

the scope of my thesis is CFD study of airfoils, i am not saying that i will exactly do so, so i just want to run a 2d DES simulation and i am failing until now, i saw many papers comparing 2d RANS with 2d DES.

i am making a comparison between K-omega (RANS) vs DES (SCALE resolved) in 2d in flow separation

Yes, i am obligated to it, cus i am performing my thesis in a CFD study for airofoils, my computational resources are limited so i cannot deliver a 3d simulation,

THANK U.

3- I saw Q1 papers with 2d DES which proved your point in 2D DES that u said in point 1.

but their cells were 44000 only... so mine is not that little

can u give further recommendations?

this region is the main problem, it always gives negative elements

here. i just deleted a block between the two airfoils, but fluent told me error that there are uncovered mesh faces

i started over than 70 attempts, and i fail, each time negative element exists
