icoReactingMultiphaseInterFoam case files

Does anyone know if the poeple over at openfoam.com have published the case files for the example they show on the website here (the first video of the melting):

https://www.openfoam.com/releases/op...nd-physics.php

I've checked the tutorials and I dont see it.

Thanks!

Hello Chris,
There are certain tutorial files available under this solver. You may please check them by installing openfoamv1812.

validation of icoReactingMultiphaseInterFoam

Hello,
I am trying to validate the solver icoReactingMultiphaseInterFoam with Stefan problem where i want to track the displacement of an evaporating liquid.

Can anyone used this solver? Is it possible to achieve this validation with this solver? Or Is there any alternate solver to do so?

Thanks in advance!

accessing alpha values

Hey guys,
has anyone tried to access alpha(volume fraction) values in this solver.I need to access them through code. can someone please explain how i can refer to alpha values?

Is there laser melting set files?

Did anyone have the laser melting set files?
I want that file for reference.

Hi Navid,

Were you able to figure out how to access the alpha phase fraction using icoReactingMultiphaseInterFoam? I am trying to reference the surface / phase change interface (grad Alpha).

Any insight would be much appreciated!

Thanks!

Thank You.

AFAIK you can gain access to the phase volume fractions using

fluid.phases()[index]

or using fluid.phase(index)

this should return the selected phase plus the scalar field

Hi,

Sorry for the late reply. The first method worked. Thanks a lot.

Hello Dear Friends,
I am trying "Laser Simulation" by using "icoReactingMultiphaseInterFoam" solver and Laser DTRM radiation model. But I am facing an error, I am unable to recognize the error. So if anyone knows about this error please let me know.

I am attaching my code file in Zip format for the reference.

Error
