inlet velocity boundary condtion help
 
I have 2 inlet ports. I wanted to give separate profile for each inlet. The problem is when i specify the names as inlet 1 & inlet 2 during meshing, it gives me an error "model information is not compatible to the mesh" as I open the fluent. But when I rename both of them as a single inlet the error is gone, but i can only specify one inlet boundary condition in fluent.

Try to separate them in Fluent by separate=>face=>region

It worked. Thanks. But I have another problem. As i have changed the model in Fluent it is asking me to implement case modification strategy for mesh changes.How do you do this?

It should be no problem since there is no significant change in grid.

When I the closed the fluent and updated the work bench, I lost all the information. I think i should probably do the "case modification strategy for mesh changes" as I am creating a new boundary.
Can you tell me how to do it?
