CFD simulation of a rotating cylinder


I have been trying to calculate lift and drag of a rotating cylinder.
1.I got error in meshing.can you help me with the meshing.
2.can i use mrf zone to rotate cylinder region?
Thank you,


Hi @bharath!

Please share the project with us here in the comment section. @PowerUsers_CFD or me will have a look at it then. And yes you can use MRF for your simulation - please also see the documentation for more information: Rotating Zones

All the best!




Hi @bharath!

You cannot use the windtunnel mesh option for MRF simulation. Please have a look at this tutorial from our documentation and let me know how things go: MRF Tutorial

Cheers and happy SimScaling!
