Default Help on the initial condition for compressible LES
Posts: n/a
Hi, all

Can somebody give me some suggestions on how to set the initial condition for compressible LES?

For incompressible flow, I know we need to let the velocity satisfying the divergence free condition. but how to deal with compressible case?

Can I still use the incompressible initial condition pluse some random noise?

Thank you guys very much!
