Hi,


My problem is that the value of solid temperature is higher than the expected value. Even I increased mesh density in solid domain but nothing has changed. The maximum value of solid temperature must not exceed 1800 K but I got 2000 k.


Thanks in advance.

I'd be more interested in working out why: we can fix temperatures and the like but you need a good reason and understanding of the why before doing things like that.

Dear rwoolhou,

Thanks for your response.

Well, I got exact results for fluid domain and my problem is just solid temperature that must not exceed 1873 but after several simulations with denser mesh I got about 1900K for maximum solid temperature, of course I did this simulation using other fluid too and didn't have any problem in solid domain and the maximum value of solid temperature was very less than 1873 but for nitrogen  the solid temperature is higher.
