Hello,
Is someone able to help me, please?
I'm using COMSOL to model a diffusion problem. I have solved it using the stationary solver. I am able to see that at steady state the concentration on the far edge is 0.025 mols, by clicking on the image and viewing the results tab.
Is there a better (more automated) way to get this value?
I would also like to know the time to reach steady state - the definition of steady state I have chosen is 95% of the concentration when solved using the stationary solver. How would I find that? So far I have used the time dependent solver, and laboriously clicked through each time point, judging when the concentration reaches 95% using the results tab.
I'm certain there must be a better way of doing this, but I'm unable to find the answer in the forum. Hope someone can help, thanks in advance.
