Hi I'm trying to run a Laminar Flow simulation where I have coupled my outlet boundary conditions to a set of boundary ODEs. I am however getting an error "Failed to evaluate variable Jacobian". I think it might come from trying to update variables for each time point.

In my outlet boundary conditions I want to use the calculate the average velocity at the outlet to calculate the pressure for the next step. etc. etc. I'm unsure if I may have programmed this incorrectly or if I need to specify the current time when trying to calculate my pressure. I was wondering if I could have someone look at my template and tell me if there is something wrong in how I have program set up the system.

Thank you,
Christian
