Dear all,

I am quite new to CFD. I am working on a single desktop PC with the following hardwares:
CPU: Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz
RAM:16 GB

I can ran parallel with 4 cores with this PC now. I am trying to simulate a 2D fishtail rudder performance for now and I am going to make it 3D. I want to use the full power of this PC to refine the mesh.

So, here is the main question:
How many cells are manageable in 2D and 3D for this PC?

Another question:
What is the time difference between single precision and double precision?
Let's assume a simulation take 1 hour with single precision. What will it be with double precision?

Any help is highly appreciated. Thanks in advance.

Kind regards,
