Dear all
i am doing a arterial flow simulation using two way FSI ansys simulation. i have used the artery as transient structural model and blood as fluent model. for the fluid inlet i have used a pulsating flow and used a UDF and outlet as pressure outlet. after i couple the solid and fluid and tried to run the simulation i am getting the below error. i am new to ansys. your valuable suggestion will be highly helpful. one screen shot of above error is also attached.
thank you.
