How can I mesh a hole in a large domain?
I want to simulate a release of gas in an open field area, but the area is very large and its length , width and height is about 6000, 2000, and 2000 meter, respectively

Can you be a bit more specific? Do you have a volume of the dimensions that you specify and want to release gas at a small hole in it?
Normally, something like that is not a problem since the cells around the area of release would be be small and cells in other areas relatively larger.
So, what are your issues?

Thank you for your answer.
But my domain is 8 km length , 2 km width and 2 km height.
The diameter of hole is 1 m.
What is your idea about distance of nodes near the hole and far from it?
For example near the hole 10 cm and far from it 100 m ?
I want to calculate the concentration of released gas far from the hole.
Is this mesh (near the hole 10 cm and far from it 100 m) can evaluate the concentration of released gas truly?
