How do I open a file in V4.0a that was done in V4.0?

Hello
I have been working on a model (fluid flow/laminar flow) in version 4.0. I just updated to version 4.0a. When I try to open my old models, I get an error saying "Could not obtain license for Batteries and Fuel Cells Module". My model doesn't use any of these modules. I could export the geometry from V4 and import it in V4a, but then I would have to repeat all the other model definitions such as fluid properties, etc. Is this the only alternative? To practically start from scratch?
Thanks!
Sylvana

Hi
most probably you had a demo version with all modules, and linked in some specific physics not in your V4.0a
Or there has been a different split of a specific physics. I suppose only "support" can help you with that

Good luck

Hi Sylvana, could you either attach the model in this thread or send the model to support@comsol.com?

Thanks Ivar and Dan
I'll upload the model then.

Hi, the model uses the Laminar Inflow boundary condition which is only available if you have one of the following modules available:
MEMS, Heat Transfer, Earth science, CFD, Plasma or Batteries & Fuel cells.
The model was created in v4.0 with the Chemical Engineering module which in v4.0a was split into the CFD and Chemical Reaction Engineering modules. If your Chemical Engineering Module was on subscription you should have got the CFD module as part of the upgrade.
If for some reason you don't have access to any of the above modules you can open the model in v4.0 and change the inlet boundary condition from Laminar Inflow to velocity. Save the model. It should now open in v4.0a without the need for any modules. You will need to specify a new value for the inlet velocity.
