temperature limited - absolute pressure limited
I,m simulating a bullet in the air (supersonic, euler). The first order stops at about 100 iterations, and the residuals jump over 1e+10 !
Here is a screenshot of the situation : http://img182.imageshack.us/img182/6...eenshotge6.png
The error message says : temperature limited to 5.000000e+03 in 1 cells on zone 2 ...and... absolute pressure limited to 1.000000e+00 in 1 cells on zone 2
Does anybody have any idea about how to fix it ??
Many thanks !!
Re: temperature limited - absolute pressure limite
solve-->controls-->limits ; and change the limite values. but it's bed solution you must adapte this cell or the grid
temperature limit to cell
Thanks that actually worked!!
still I am not sure why the temperature would be so high....
I have a cylinder which is receiving a heat flux of 15000 and it says temperature for 2345678 cell is 1.5e4 which is the same value as the flux. I am assuming this cell is near the wall.
Hypersonic Flow Over Cylinder ( Temperature very high~280,000)
I am modeling hypersonic flow (Mach 24) over a cylinder. I also faced the same problem where I am getting a temperature around 280,000 which does not make any sense.
I wonder if it is because I have assumed constant specific heats. But I feel something else is wrong here.
I have attached a picture of the temperature profile and boundary conditions. Any advice would be appreciated.
