Hi,
I have implemented this MHD problem following the case published in GitHUB https://github.com/ElmerCSC/elmerfem/tr ... ntHartmann.
Unfortunately I don't manage to understand why it doesn't convergence with this Velocity Profile:
Indeed, previously, I had used another velocity profile with the same geometry and case.sif and the simulation was running without problems. The mesh is at this link: https://we.tl/t-ibUaT9s9bs. Thanks in advance for your help and answers.
Regards,
Andrea
I was informed that the FlowSolver, stokes does not like a complete do nothing conditions on the inlet and outlet, so I made velocity 1 at the intlet and outlet (tangential to the in and out) and it is converging.

Hi Kevin,
Could you share please your case.sif ?

Hi,
I have tried, but it doesn't converge unfortunately. I attach the image. The velocity profile in the initial condition should be kept during the time in the interface,namely from 0 to h*h1 along x.
