In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. Using OpenFOAM, we simulated the extrusion of filaments and droplets into a moving bath, for single filaments, single filaments being disturbed by a nozzle, and printing pairs of filaments. OpenFOAM is an open source computational fluid dynamics solver. This repository contains the following Python tools: Tools for generating input files for OpenFOAM v1912 or OpenFOAM v8 tailored to a nozzle extruding a filament into a static support bath, Tools for monitoring the status of OpenFOAM simulations and aborting them if they are too slow, Tools for moving output files between storage locations. (For example, it can automatically move all files to a server, but only necessary files to your hard drive), Tools for generating images and tables from the 3D time series, Tools for compiling images into videos, Tools for analyzing, summarizing, and plotting data.
