Hi I am having troubles with a boundary contition that is not applicable. I am wondering what the reasons for this might be? I have attached my file for reference. I am trying to apply a pressure to the faces of the blood vessel and they are saying tha they are "not applicable".

You haven't selected any domains under your Laminar Flow physics, even though this is the only physics in your model. As a result, from the perspective of the code, no physics-related boundaries exist. To correct this, in the Model Builder, click on your physics (which is "Laminar Flow.") In the Settings tab, expand Domain Selection (if it isn't already expanded). Now, select some domains! You should notice a difference.

Thank you! I am new to the software as our teacher kind of just threw this project at us wihtout any instructions and this is probably a super simple fix for someone that is familiar with it. I am familiar with Abaqus and so far I like Comsol a little better.

Hi Nick,
To new users, I strongly recommend the videos in the Learning Center. In a relatively short amount of time they give you a solid introduction to the fundamental features of the software. With that fundamental knowledge you can then jump to more advanced materials if needed, like the software's documentation, etc.
Best,
Jeff
