Initialization using another simulation result
 
Hi,

Is it possible to initialize a simulation using the flowfield from another simulation (which is what I sometime do in CFX)? For example: for the same fluid domain and boundary conditions can I run a DES using a RANS calculated flowfield as the initial guess.

Thanks

Hi,
for different geometries you can use the "interpolate" feature in Fluent: File / interpolate...
For the same geometry, I think it is even recommended to start with a RANS converged flow field before running LES. you just switch to LES and transient after your model has converged.
Marion.
