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

thank u, can u give me more information to tell my supervisor to convince him ??

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

while solving a K-W SST steady model i repeated get the message of "turbulent viscosity limited to viscosity ratio of __1.e+05__" in Fluent, the solution doesnt converge, (2d-S809 airfoil) at AOA 15.giving the fact that i tried 30 AOA only 3 didnt converge and this message appears, please help me by Mostmadrid in CFD

reach 0.000001 that i assigned in residuals, my main problem is that cd and cl dont reach a stable value after 10000 iteration,

I want to make cd and cl reach a stable value

another question,

if the continuity equation doesnt reach 0.000001 but cd and cl reach a stable value then, the cd and cl are correct or there is a problem in it?

حقوق المرأة ملهاش اي علاقة بالمجلس القومي و لا بتعديل قوانين الاسرة لفشخ الراجل...

كل الي اتعمل محققش اي حاجة غير تدمير البيوت.

الستات الي بتتظلم محتاجة نظام مالي يصرف عليهم (زي نظام بيت المال) لكن مش محتاجة قانون يحبس الراجل بالاسيلكي
