This software is designed for simulations of mold filling and curing in resin transfer molding, a manufacturing process for continuous-fiber reinforced composites. It is based on OpenFOAM-6, a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. Relevant extensions presented in of-rtm-6 consist in heterogeneous and porosity dependent permeability, resin cure and cure dependent transport modelling.
This software originates from KIT’s Institute of Vehicle Systems Technology (FAST), Division Lightweight Engineering (Prof. Kärger).
For instructions on how to set up the project locally, the user is referred to the OpenFOAM installation instructions. For the usage of the RTM extensions please have a look at the RTM tutorials:
- Brinkman - permeability model verification case with the Brinkman equation for a channel with different permeabilities. See e.g. Syerko, 2017.
- Bruschke - RTM verification case after Bruschke, 1990 for a plate with for quadrants with different fiber orientations.
- IRTM_test and CRTM_test - Simple 2D RTM case of a rectangular plate filled with a linear injection and a constant flow rate. Plate should be filled until 50% in IRTM_test and then Compression starts (tutorial CRTM_test). CRTM_test uses result of IRTM_test as start. After both tutorials you can run `gnuplot pressures.gnu` in the main tutorials folder. The file “pressures.pdf” is generated and should give the same result like the analytic solution plotted.
- L-Section - L-shaped geometry with linear injection, **cure kinetics and cure viscosity**.
Description and examples from RTM tutorials. See also the OpenFOAM documentation and the source documentation.
