hello, can u tell me that, when i am meshing a curved surface in gambit a new line is coming which is not superimposed on the actual profile, and this new line is meshed, will this create trouble in fluent, (bcoz my solution is not converging, residuals are stabilized) if yes what is the remedy?

I suppose this "new" line is the meshed one... Try to use more nodes and maybe you will get close to the desired line...

Let's say that this will simplify the geometry of the object...

ok, i will try that, and there is another thing that is creating problem to me, my solution is not converging, residuals are stabilizing, i had tried almost every solvers, my problem is compressible, pressure in let and pressure outlet, with periodic top and bottom, and blade with no slip, velocity is not so high its around 60 m/s at inlet, and it is a gas turbine, so velocity is increasing at exit(not more that 1.3 mach no.) can u plz suggest me the solver, m using pressure based, steady, implicit, second order every where, simple in pressure velocity coupling, etc,
it will be very grateful if u can! this is 2-D till now. |
