January 25, 2021 at 2:53 pmcarlotaSubscriberI have a valve with more 6.000 faces and i reduced to 300 because ansys dont work with a lot faces... and i want to know two things: n1.- Is there any way to reduce the faces so that they are close enough to the original geometry? Which program do you recommend? .. I tried fusion 360, but I would like to reduce better and fix the edges.n2.- Can i work with the valve and flow without FSI in ansys fluent? I'm only interested in modeling the fluid but I need it to go through the valve. nn
January 25, 2021 at 3:42 pmRobAnsys EmployeeWhat sort of valve? We have a few moving mesh options in Fluent so it's very likely one of them will work efficiently. n
January 25, 2021 at 4:03 pmcarlotaSubscriberIs a mitral valve. nArrayI need to reduce the polygons of the valve and fix the edges, then insert it in a tube, but I don't know if I can put the valve without FSI, I am only interested in the fluid.n
January 25, 2021 at 4:13 pmYasserSelimaSubscriberAnswer to 2) Yes you can model the flow without FSI. Just draw the geometry of the flow field (valve enclosure) and import it to fluent. Then set all the interfaces with the structure as walls.nFor 1) If the geometry is large and you are limited by the number of cells/faces ... make very coarse mesh where you are not expecting gradients and refine the mesh close to the wall. This would be good to obtain preliminary solution. I can see you geometry is complex and it is difficult to control the mesh size in different locations. Try making parts.
January 25, 2021 at 4:19 pmRobAnsys EmployeeNote, staff are not permitted to open attachments, but Google was very instructive. You'll need to define the motion which won't necessarily be simple given the shape. One option is to look at the intrinsic FSI inside Fluent or use a very much simplified valve shape & motion to prove the concept: that depends on what the purpose of the simulation is.n

Boost Ansys Fluent Simulations with AWS
Computational Fluid Dynamics (CFD) helps engineers design products in which the flow of fluid components is a significant challenge. These different use cases often require large complex models to solve on a traditional workstation.
