Hi,
I am a student with very minimal experience with COMSOL (most of what I know, I have learned just from experimenting with the program). I am modeling fluid flow through a flow chamber (see attached model). COMSOL was able to find a solution when I ran the study for this model in an older version (either 3.5 or 3.5a, I can't remember). However, now that I have updated to 4.2a, running the same model fails to find a solution (Error message is "Maximum number of Newton iterations reached.") I have tried different mesh sizes, without success.
Since I am not familiar with the commands and capabilities of 4.2a, I am hoping someone can direct me toward where I am going wrong. I have attached images of some results I obtained from running the model in the older version (Reynolds number and velocity field slices). I need these results to be verified when I run the same model in 4.2a, before I can move on to redesigning the chamber.
Thanks!
