Reply To: microFluidics2d: Including gravity


Hi Callum,

the microFluidics2d example uses a phase-field model that might be incapable of simulating a high density ratio such as water/air. For this, you can use the model from the example “phaseSeparation3d”. It is a pseudo-potential approach that uses Carnahan-Starling EoS. With the right reduced temperature, the EoS will give you a density ratio of the water/air system. The implementation with this model is easier, too, as you will only need one lattice.

Best regards,
