Detailed Description

The post process module provides all the useful procedures that the user and developer will need to compute various data processing. It is divided in sub modules which you can use to compute physical diagnostics (for example the wall shear stress, see Diagnostic quantities) or do elementary operations such as the \(L_2\) norm of an error field (see Error tools).

Make sure to visit the [validation post process framework] (Validation) page whenever you need to analyze numerical convergence.
