Hi, I get the display of density as checker board (like distorted pixel image)...without any variation in the value. I am not using ideal gas.. What can be the reason? Regards

if you look athe schale, you will probably see that the minimum and the maximum are the same. My guess is that you are looking at a uniform density field.

suggestions: change the scale as such that min and max are at least slightly different. Do you see the constant density field? If so, and if you think density variations in your flow problem are important: do not use a constant density material.
