Error message: Variables not coupled to any degrees of freedom (details: mod1.qYZ1)

Please login with a confirmed email address before reporting spam

Hi everyone,
I am running a simulation with a model consisting of a solid block with a fluid cylinder running through it. Study 1 is a transient study solving just for the fluid flow (the inlet velocity is pulsatile). Then I have a Steady-state parametric study solving for the solid mechanics portion of the problem, using the pressure from the fluid flow solution.

The simulation worked once, but I changed something and can't figure it out. If I'm just running the fluid flow study, what could possibly be giving me the error message:
"Variables not coupled to any degrees of freedom - details: mod1.qYZ1"

I'll attach the file as well if anyone wants to take a look. Thank you!

Austin
