DNSlab is a software for analysis and direct numerical simulation of fluid and particle flows by means of 3D models especially of microscale porous structures.

The new DNSlab Python Interface was introduced with the first DNSlab release in 2024, Release2024a. It enables DNSlab users to automize and customize the pre- and postprocessing of DNSlab applications. The interface is provided in the form of a package of classes and functions which are imported in the user’s python code, and which enable to read and write DNSlab input and output data. The basic working principle is that by the user’s python code, DNSlab runs are prepared, executed and evaluated. In particular for the evaluation, Python’s comprehensive plotting capabilities are applicable.
