Hello,
I did a test in a small case using CS 6.0.4 and the temperature field in celsius. I used LES dyn model restarting from K-omega SST and I don't get this behaviour in the temperature iterations. Maybe it was a bug that was fixed in the subsequent versions.
Regards,
Luciano

Re: Different convective schemes for different zones
Hello Ok, but setting different blencv in your domain you are mixing first and second order schemes. May be the ischcv = 3 ( Blending between Second Order Linear Upwind and Centered scheme) is what you need, because your will be using two second order schemes and the unphysical oscillations can be r...

Re: Different convective schemes for different zones
Hello,
Did you try with another convective scheme like SOLU (ischcv). Also, you can set different limiters (isstpc)

Luciano

Re: Store surface normal vector to array in parallel simulation
Hello, I think that before call cs_parall_allgather_r() you have to do a parallel sum (parcpt) in order to sum "nlelt1" to get the total "n_g_elts". After you get "n_g_elts" you can call to cs_parall_allgather_r() Let me know if I'm right, because I never use it in CS, ...

Re: Store surface normal vector to array in parallel simulation
Hello, After partitioning the mesh each process will have a portion or not of the boundary WALL1, so each process has to create a local array and then you need to join all these array with a mpi gather. You can take a look to the file cs_user_extra_operations-parallel_operations.f90 in the example d...

Re: ibeta
Hello, ibeta it is a (integer) pointer for thermal expansion coefficient. To access to the thermal expansion coeff you can use this example used inphyvar.f90, I think. double precision, dimension(:), pointer :: cpro_beta .... .... if (ibeta.ge.0) then iok1 = 0 call field_get_val_s(ibeta, cpro_beta) ...

Re: Breaking the GUI
Hello,
I download your xml and can't reproduce you error. I make some changes and save it without any error or warning.
What version of CS are you using?

Re: thermal expansion coefficient
Hello, First of all you have to activate the thermal model, then in the fluid property tab change density from constant to user law. In the mathematical expression editor you can write an equation for the density which include the thermal expansion coefficient, like the Boussinesq approximation for ...
