This panel allows you to perform basic postprocessing calculations.

Normally output from solvers consists only of the basic fields like pressure, velocity and temperature. It is often necessary to obtain certain derived fields and values. This values can be obtained in the **Calculate** panel.

There are three basic types of post-processing calculations:

**Fields**– calculates derived fields such as Mach number or vorticity**Wall**– calculates derived fields that are important only on walls, such as y⁺.**Boundary**– calculates values at any mesh boundary

All the calculations can be performed on demand using the **Calculate** button. This button will not be active when there are no results available or the simulation is still running.
