Hello all. I'm currently trying to model (roughly) the effect a stent would have on blood flow into an aneurysm, and I ran into a problem with the flow simulation where it says I have zero volume. The model is attached.
When I run a fluid analysis on the assembly without the stent, everything works just fine and I get a non-zero fluid volume when I check the assembly's geometry, as shown in the first picture. However, when I put the stent into the assembly and checked the geometry, the fluid volume shows up as zero (second picture). Any idea what could be going on? At first, I thought it was because the stent's position was under-defined, but after adding a lock mate to fix the stent's position, the result is the same--zero fluid volume.What could the stent be doing that is making the model not work?
Any help is greatly appreciated! Thank you.

Brando,
When I tried to get the fluid volume, there is an error message that the boolean operation failed. It seems Flow Sim is having trouble with the complex geometry of the stent. You could try making a simple version of the stent without the diamond shape hole patterns. You could also try one that is not made using the Flex features, but made with a sweep or extrusions. Then, see if the fluid volume check works. This might give you some idea of what geometry features are causing the problem. You might want to send this one in to Solidworks as well. They might have some insight as well.
Good Luck,
Eric
