it is impossible for NUMECA to give such estimations.
it needs exprrience and can be only done by user approximately.
in fact it depends many parameters like:

-mesh type (sturctures, unstructured)
-mesh sizes
-flow field geometry (shape and dimensions)
-flow regime (laminar or turbulent)
-near wall treatment method applied
-turbulence model used (if any)
-initial conditions
-convergency criteria
-time dependency of flow (steady or unsteady)
-subsonic or suppersonic flow?
-single or multi phase flow?

each of parameters named above can affect run time.

Regards
