Hi! I am getting the error code 7220 when trying to solve the attached model. The solid structure is under a load produced by the fluid as well as a load of 0.0076 N/m^2 on curve 1. The fluid is flowing due to a difference in pressure. The pressure at inlet (curve 1) is 200,000 Pa and the pressure at the two outlets (curve 5 & 9) is 0 Pa. If I highlight only u,v,x, and y on the Solver Manager, the model will solve for the solid subdomain but not the fluid subdomain. I would like to be able to solve both the solid and fluid subdomains without the error message. Please let me know what I can do to fix the model. Thank you very much!
