Two-temperature model of electric arc

Hello, everyone, I am going to build a two-temperature model of an electric arc plasma torch. It implies separate temperatures (or enthalpies) for heavy particles (molecules, atoms and ions) and electrons. The electric arc is non-transferred and can burn in re-strike mode. I need two-temperature mod...

Re: Compile the case on another computer before execution

Thank you for your answer, Yvan. Unfortunately, I cannot use Code_Saturne from the terminal and I do not have GUI. I have to start all the calculations with a script for Slurm just by typing "sbatch script_for_calc.batch". The script currently looks as following: #!/bin/bash #!/bin/bash #S...

Re: Electric conductivity is outside of the Argon range

Thanks a lot, Yvan. I found the problem. I have imposed the value of electric potential gradient instead of the scalar product of the electric current vector and the normal vector. I just had to read the user guide more carefully. Also the idea to choose "user defined" for scaling was corr...

Re: Electric conductivity is outside of the Argon range

Thank you for your answer, Yvan. Could you please tell me, what should I specify in the Electrical models/Electric arc/Variables scaling model? If I want to impose electric current as a boundary condition, I do not need any scaling here, right? But if I just choose "user defined", the elec...

Electric conductivity is outside of the Argon range

Hello everyone, I am trying to build a simulation of electric arc in Argon with imposed electric current density at the cathode surface instead of imposed electric potential difference. Hence, the boundary conditions are as following: Anode: Pr=0.0 Cathode: grad(Pr) = |-J(imposed surface distributio...

Re: Compile the case on another computer before execution

Thanks a lot for your answer, Yvan. I think, it is the case for me: compilation doesn't work on the compute nodes. So I need to discuss it more with the administrator. I just hoped that the compilation could be done without problems on a virtual machine with Ubuntu and then sent to the cluster. Coul...

Compile the case on another computer before execution

Hello everyone, I need to use Code_Saturne on a HPC cluster with Linux. But the cluster cannot compile the code for some reason, which is not clear for me. As far as I understand, it will work if I compile the code on a separate computer and then just copy the compiled code to the cluster. Does some...

Re: How to choose hardware for electric arcs simulation in C

Thank you for your answer, Yvan! As far as I understand, the processor clock rate doesn't have a big impact to the computation speed, right? If I choose among different Intel Xeons should I take more cores or a higher processor clock rate? Could you please advise something for the RAM and the mother...
