This way, it is demonstrated that comparable performance can be achieved for problems with locally highly refined grid.
The model is assessed in transient, planar turbulent wake flow simulations over a square cylinder utilizing progressively refined grid.
Secondly, a pre-cracked plate with an off-centre circular hole is simulated under tension condition to assess the performance of locally refined grid.
Results indicate that all codes produce a very similar solution for the non-reacting flow in terms of large scale unsteady vortex shedding behavior, mean profiles and second order turbulence statistics, on a suitably refined grid.
Of course, it should be more precise to use the fully refined grid as the reference.
