I am working human artery where objective is to study fluid interaction.It consist two part in first part i did CFD study in second part i am doing structural analysis.diameter of artery is 2.17 mm,thickness of wall is 0.9 mm,length of artery is 20 mm.I run CFD simulation using non Newtonian power law.Boundary condition for cfd at inlet is velocity inlet and its value is 1.116 m/s and outlet is pressure outlet.I completed cfd study now for fluid intraction study i imported my pressure data into ansys static structural analysis.Main problem ariese here.

Property of material in static strcutural analsysi i am using- initial shear modules -3000 pa,incomprehensibility parameter - 6.67e-06
I kept fixed condition at inlet in outlet in structural analysis..I imported pressure from ansys fluent.Now when i run the simulation artery get deformed and I am getting this error every time "The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information."
i increased sub step but same thing is happening. Please help me figure out this.I am facing this problem form long time.

I modeled 3d cylinder with 3mm thickness by static structure problem emerged when I imported my model to workbench , there was no problem with messaging it but I suffered from putting 2.5 mpa pressure on the internal surface for studying stress ...there is no internal surface on the surfaces when I want to define internal pressure ...may I get any answer for this case plz
