ParaSiF_CHT_Development

This repository contains the ongoing development of ParaSiF new feature on Conjugate Heat Transfer between FEniCSx and OpenFOAM that to be integrated into the ParaSiF Parallel Partitioned Simulation Framework once mature. It is maintained as a submodule of the main ParaSiF repository: ParaSiF Main Repository. Please note that all dev-submodules will not be shown in the main ParaSiF repository for users.

Overview

Ongoing development of ParaSiF new feature on Conjugate Heat Transfer between FEniCSx and OpenFOAM via the MUI coupling library.

Key features to be developed:

• Thermal conduction in solid domain
• Conjugate Heat Transfer between fluid and structure domain
• Conjugate Heat Transfer between two solid domains
• Thermal expension in solid domain

---

Compatible Codebase

This solver has been tested and is compatible with FEniCSx v0.9.0 and OpenFOAM v2506.

Users are recommended to use this version to ensure full compatibility with ParaSiF FEniCSx solvers.

Installation

Note: This new feature will be a part of ParaSiF. Follow the main ParaSiF repository instructions to initialise submodules and install global dependencies.

Steps

1. Obtain and install the codebase

   • Initialise the FEniCSx and OpenFOAM submodules from the main ParaSiF repository.
   • Ensure the FEniCSx and OpenFOAM submodules in the main ParaSiF repository are correctly installed by following their instructions.

2. Install the OpenFOAM solver in this repository To Be developed

Running Tests and Example Cases

Benchmark cases are located in the test/ folder:

Steps

1. Navigate to the desired benchmark folder:

cd XXX/test/XXX

2. Run the simulation:

./Allrun.sh

3. (Optional) Clean up previous results before rerunning:

./Allclean.sh

4. Check results:
