Convergence validation on transient simulation
Good day Altair community,
I'm looking for some advice about the interpretation of the residual and solution graphs, I´m struggling to determine if my simulation is converging. I used a convergence tolerance of 0.0001 since default tolerance didn´t give me the precision I was looking for on the results. So, according with the graphs, could you tell if this simulation is actually converging? If not, what could I do? I can give more details of the simulation if needed.

Along with sections here:
I would suggest this is not converging - likely need both more mesh and smaller time steps.
