Solid Mechanics - Failed to find a solution.

Hi,

I am trying to simulate how a catheter deforms, when pushing against a vein. It's a fairly complex catheter (as it is imported from CAD) but a "easy" vein ostium.

I set the boundary load at the end of the shaft with 0.2N and the Fixed contraint on the outside of the vein ostium.

The outter cylinder as well as the cylinder and the cone around the catheter are not used in the solid mechanics module but for another stage later.

I already tried to use Symmetry as the catheter is symmetrical for 1/5 of the circle (see 2.png).

Is there a better way to get this result? Could it be a problem, that the catheter and the ostium aren't in contact yet?
