Hi,
I am using v5.0 and I am having this error. My model solves for heat transfer, fluid flow, and vapor transport. Any help would be very appreciated.
Thanks!
Jessica

Hi Jessica
You probably have used the results of a previous study as the initial condition, which has been solved with different mesh configuration.
Try to use the same mesh for both.
If you have not done so, delete the whole study and define a new one.
Amin,
