Thank you for your reply, the problem is setting up the ramp condition, whenever I switch from a fixed value to a table value, the simulation returns with “an error has ocurred” and after checking the log, the simulation was not even able to start. I made a new run in the proyect with this settings, the error persists. The ramp recomendation was from this post
I was using the slip wall condition to get a preliminar result to get a little more stable simulation; my logic was that it shouldn’t crash as easly if I do not try to solve the boundary layer.
Thanks a lot will do it and try!
