Looped visual sequence assembled from the 27%, 53% and 80% solver snapshots. The dissolves are transitions only, not additional simulation results.

Development process

RIM Studio is a desktop application I developed with AI assistance to bring the preparation of RIM (Reaction Injection Moulding) simulations into a visual workflow.

From model to simulation case

The tool starts with closed STL models and uses OpenFOAM Foundation 13. It allows users to select inlets and vents on a 3D view, set orientation and adjust material, mesh and filling parameters.

Filling and curing

The project documentation describes one- or two-component VOF filling, Kamal–Sourour curing kinetics and cure-dependent viscosity. The workflow produces visualisations and data for exploring example cases.

The images show three stages in filling a demonstration cavity: approximately 27%, 53% and 80%. They are not an industrially validated part or an experimental comparison.

Scope and limitations

This is a preliminary engineering tool under development. The model is isothermal and post-filling cure is integrated locally, without flow. Example materials are indicative: the application does not replace material characterisation, process testing or simulation validation.

  • Filling simulation: resin at about 27 percent of the demonstration cavity.
  • Filling simulation: resin at about 53 percent of the demonstration cavity.
  • Filling simulation: resin at about 80 percent of the demonstration cavity.
