Solidworks COMSOL fluid flow (air) simulation

Please login with a confirmed email address before reporting spam

Hi everyone,

I was wondering if anyone here knows if COMSOL can simulate Solidworks models straight from import. Here's the scenario:
1. import solidworks model of a pipe with a hollow x-diameter
2. using COMSOL, simulate an air flow through the pipe at y-pressure at the inlet

Based on what I've read in online tutorials, all examples require a 'solid' geometry of the flow area in question. Thus, this would require me to modify the model to make the inside diameter a solid.

Is it possible to model fluid flow while keeping the original solidworks model design (i.e. flow inside the hollow pipe)? It doesn't seem practical to always modify my models to make them 'solids' in order to run COMSOL fluid simulations. For instance, what happens if I have a SolidWorks model of the capillaries in the lung (i.e. many, many branches) and I wanted to simulate the air flow through it using COMSOL? It would be impractical to modify the entire system to make it solid capillaries.

Thank you in advance.
Regards.

Hi Ronnie,
There's a tool in COMSOL to do exactly that, it's called Cap Faces. Please see www.comsol.com/blogs/meshing-cap-off-for-cap-on/ .
