# openInjMoldSim [`v7.2`](VERSION.md)

[![DOI](https://zenodo.org/badge/92510370.svg)](https://zenodo.org/badge/latestdoi/92510370)

This is an [OpenFOAM](https://en.wikipedia.org/wiki/OpenFOAM) solver for simulation of injection molding filling, packing and cooling stages.
It is a modification of the compressibleInterFoam solver distributed with OpenFOAM.
Currently, the simulation is prohibitively inconvenient for typical industrial use but it can be helpful in research because it can be customized.

## Getting Started: [watch video](https://www.youtube.com/watch?v=aNC0CqfDyT0)

An [OpenFOAM 7 installation](https://openfoam.org/download/archive/) is required to run the code.

Run `./Allwmake` in the solver directory to compile the code.

To run the dogbone case, set the `numberOfSubdomains` in the [`decomposeParDict`](/tutorials/demo/dogbone/system/decomposeParDict) according to
your machine. Run `./AllMesh` and then `./AllRun` in the [`dogbone`](/tutorials/demo/dogbone) directory to run the example simulation. Then run `paraFoam` in the case directory to view the results.

## Functionality

* Compressible, non-isothermal, laminar cavity flow.
* Tait equation of state.
* Cross-WLF viscosity model.
* Specific heat and thermal conductivity may depend on temperature and pressure (tabular form).
* Elastic stress in the solid phase.
* Fiber orientation (openInjMoldSimF).
