Hello everybody!

I'd like to invite anyone who's interested to try out our solver for injection molding https://github.com/krebeljk/openInjMoldSim. I'd be very grateful for any kind of feedback.

We implemented the Tait-equation of state and the Cross-WLF model in compressibleInterFoam from OpenFOAM version 3.0.1 and named it openInjMoldSim. Along the solver there are four cases: a demo case for filling and packing and three tests.

The demonstration of filling and packing compares the simulated pressures with experimental values. The cavity is modeled as a 2D case. The experimental pressure evolution from the first measuring position is imposed at one end of the cavity and the other two positions are compared.

The validations test

• the Cross-WLF viscosity in a perfect shearing flow at a particular temperature,
• the heat transfer coefficient in a quasi 1D dimensional heat conduction case and
• the Tait equation for a confined material being heated and pressurized.

The cases include gnuplot and python scripts to plot the results.
