Hello,

OK I'll try this. Thanks a lot for the help.

Hi, I’m running a coupled simulation of gas mixture with thermal effects (H2 in air). As the mass flow injection of the second gas is really low, once I’ve reached the thermal convergence, I’d like to accelerate the calculation by solving only the transport of the user scalar representing H2 (with f...

Hello,

thanks for the location of post_util file.

For the test I made on getfbr, I'm running each code on one rank (one for C_S, one for Syrthes).
For the calculation, I run it with one rank for Syrthes and 15 for Code_Saturne.

Fanny

Hello, Concerning the calculation of the Nusselt number, I'm using using this formula to stay as close as possible of Results I get from an article. Once I get good enough results this way, I'll take a look at the the calculation of Nusselt using wall temperature or temperature gradient (on the basi...

Hello, I’d like to know if there is a function working like ‘getfbr’ when coupling Code_Saturne with Syrthes. In fact, I wrote a function computing the Nusselt number on the boundary between solid and fluid meshes. It works when starting Code_Saturne only. But when I launch a coupled calculation, th...

I thought I had to intialise an array either with a loop over is components, either by multiplying it by an array of the same size.

With your correction, it works just fine.
I'm still wondering why it worked on one proc, the error was (once again) a silly one. But whatever.

Thank you for your help.

Hello, I’m doing a classical simulation of the buoyancy driven mixing of two fluids in a sloping channel. The simulation gives good results, but I’m having some worries with the computation of front velocity when running parallel simulation. I’m working with a 2D rectangular and uniform mesh, x bein...
