In Ansys Fluent, Cell Zone Conditions>Operating Conditions, What is the significance of the Variable-Operating Density Parameters?
On what basis one should determine the value?
In ANSYS CFD-Post, the entity Pressure I see while defining Contour, does it show relative pressure above the reference pressure defined for the concerned domain during CFX- Pre? i.e. Is it...
