![]() If you have just the two phases (oil, water) AND you are using interfaceCompression between them (this can be switched off in multiphaseEulerFoam) then you could use a clip on the scalar alphawater (0.5 is fine) and then color as a solid color. Well, it sort of depends on what you are actually trying to simulate which is still not super clear to me. Wondering I chosen the wrong value for clip scalars, however, before knowing the mechanism, I am not sure what is right to choose.ītw, the solver what I used is multiphaseEulerFoam I use the same method, but this time I can only see the water base but without and different colored oil on surface of the water. The rest is to use the clip to scalar optionīUT, only I can see the water-in red color when it falls into the oil, how can I see the effect like the one plotted by the contour but with different color? If I use contour the result would be like the first photo I use three value 1.0 1.1 1.2 to make sure you can see the surface of the oil. Can you please explain how this value matters? You are correct, the base is oil and the droplet is made of water.įor the clip scalar, I am not sure what should I choose( alphas, alpha oil or alpha water?) to render and what value should I put ( I tried alphoil with value of 0.5 as in photes). Thanks very much for the help and you really gave me a good way to start with. īut CFX or Fluent can handle this easily in their pre-process.while its tough in OpenFOAM.ĭo you know how to handle this? by the way, you have so many cells, how small is your time step? and which program are you use to generate mesh? but this innerface should not emerge in the boundary dictionary.you can see it here. There is always an innerface which can not be deleted. such as unstructured mesh in rotatezone and structured mesh in stationaryzone. It works too but a smaller time step.īut problems arise when I am using hybird meshs. or just generate tow bodies called rotate and stationary. then set the innerface as interior or interface. for example: I generate block in the entire zone and name it seperately rotatezone the stationaryzone. I generated mesh via ICEM, but I can only make the solver working without exploding by the same mesh in ratate zone and stationary zone. ![]() I am do the simulation using MRFInterFoam or twophaseeulerfoam, but I have big problems in MRFzones. Thank you Kent, Thats a splendid post-processing job u have done. "Open-Source CFD Simulations of Liquid–Liquid Flow in the Annular Centrifugal Contactor," Sep. The mesh had ~2.5M poly cells (made in ccm+). This was done using multiphaseInterFoam, version 1.5.x.
