While running the standard k-w model on double precision 3D flow following error message flashed on my screen:
Error: 1000000: Failed to allocate 42.05MB memory
How to find solution of this problem?

You need more memory... RAM

So should I utilize simple three dimensional modeling without using Double precision?

Yes, Single precision uses less memory than Double precision

But does this affects the precision of converged solution if we are modelling for trailing vortices shedded from an airfoil?
