- Delivery mode
- desktopobertscheiderfhwn.github.io · read 24 Sep 2026
- Extensibility
- Additional equations, such as degree-of-cure modeling, can be added, and existing equations can be modified for cases such as variable cavity thickness.obertscheiderfhwn.github.io · read 12 Oct 2026
- GUI
- The GUI can start and continue simulations, inspect meshes and plot filling and pressure distributions.obertscheiderfhwn.github.io · read 11 Oct 2026
- Headless limitation
- The repository README says running RTMsim on headless machines is currently unsupported due to package GLMakie issues.github.com · read 12 Oct 2026
- Inlet selection
- Users can select inlet ports interactively, and the tutorials describe cascade injection using additional inlet ports.obertscheiderfhwn.github.io · read 11 Oct 2026
- Installation requirement
- RTMsim was developed and tested with Julia 1.8 and is installed through Julia’s package manager from its GitHub repository.obertscheiderfhwn.github.io · read 12 Oct 2026
- Intended users
- The documentation describes using filling simulations during mould design to study inlet and vent placement and avoid incomplete filling or trapped air.obertscheiderfhwn.github.io · read 12 Oct 2026
- Interface and plotting
- The GUI supports mesh inspection, simulation start and continuation, interactive inlet selection, and plots of filling and pressure results.obertscheiderfhwn.github.io · read 12 Oct 2026
- License
- The public repository identifies RTMsim as licensed under GPL-2.0.github.com · read 12 Oct 2026
- Linux limitation
- The Linux GUI is described as experimental, and the documented Linux workflow runs simulations from the Julia terminal.obertscheiderfhwn.github.io · read 12 Oct 2026
- Linux support
- The Linux GUI is described as experimental; the guide documents running simulations from the Julia terminal.obertscheiderfhwn.github.io · read 11 Oct 2026
- Material properties
- Users can specify preform thickness, porosity, permeability and principal permeability directions for multiple regions.obertscheiderfhwn.github.io · read 11 Oct 2026
- Mesh accuracy
- The documentation says a mesh refinement study is needed because coarse meshes can predict filling time with an error of approximately 20% in the described case.obertscheiderfhwn.github.io · read 11 Oct 2026
- Mesh input
- The simulation uses a three-node triangular shell mesh on the part’s mid-surface, which must be generated with a separate meshing tool.obertscheiderfhwn.github.io · read 11 Oct 2026
- Mesh limitation
- RTMsim does not include mesh generation; a compatible triangular shell mesh with predefined regions must be prepared separately.obertscheiderfhwn.github.io · read 11 Oct 2026
- Model capabilities
- The documentation says the model targets accurate filling patterns and filling times and supports non-isotropic preform permeability.obertscheiderfhwn.github.io · read 12 Oct 2026
