Cerebral Aneurysm

Good morning, I'm simulating the blood flow in a brain aneurysm. I made a 3D geometry (aneurysm.mph) where the internal domain is blood and the external domain the artery. I set the following boundary conditions: I consider a laminar flow, with a pulsatile flow rate at the inlet as in fig.1 and at the outlet with zero static pressure. For the material properties I inserted a blood with 1060kg/m³ density and a dynamic viscosity of 0.0036 Pas, while the artery properties are in figure 3. The study selected is 'FluidSolid Interaction, Fixed Geometry'. I did a stationary study (with all default parameters), but I have got some problems. Probably the geometry is wrong. If someone can help me, I will be grateful. Thanks a lot.
