Compressible Dynamic LES Models
 
Hello Foamers and good day to all. Question, is anyone able to run any dynamic compressible LES models starting at time=0? I inquire of such a question because, it seems I have to initialize the flow with a static compressible LES model. Thereafter, I am able to utilize the compressible dynamic LES models. Can anyone kindly give me feedback on this issue?

Cheers,
Deji

Problem solved. The issue was initializing sub-grid scale viscosity and thermal diffusivity to zero; changing the initial values to something other than zero, such as 1e-08 resolved the problem.

Cheers,
