How to incorporate Dynamic mesh in SOLVER eg InterFoam-InterDyFoam to say another

saddy · May 17, 2017, 06:37

i have been working on interThermalPhaseChangeSolver [CUSTOM MADE]to model boiling phase change.[OPENFOAM[
however i wish to incorporate Dynamic mesh just like interFoam has InterDyMFoam which involves dynamic VOF interface tracking. this saves/reduces computation time about ten folds.[OPENFOAM]
but how to include in my solver i have no idea. which files i have modify and which more codes i have to write???
does any fellow foamers have any idea?

Hi, How did you incorporated dynamic meshing in your phase change solver?

interThermalPhaseChangeSolver sounds like it is based on InterFoam. Have you written it yourself? I would try implementing the phase change in InterDyMFoam, instead of implementing the dynamic mesh in your custom Solver.

If your custom solver is based on InterFoam, this shouldn't even be tooo hard.

Hi,

I am trying to incorporate Dynamic Mesh into phaseChangeHeatFoam. phaseChangeHeatFoam is basically modified version of interFoam. I tried to convert phaseChangeHeatFoam into dynamic mesh solver in similar way like interDyMFoam by replacing and modifying the existing files of interDyMFoam. But the solver shows floating poing exeption error (core dumped).

What can be the right strategy to convert phaseChangeHeatFoam into phaseChangeHeatDyMFoam?

There is a solver interPhaseChangeDyMFoam, which does almost what you try to do. Understanding you are trying to implement somewhat of an energy equation, you maybe want to start here.

A good starting point is, to look at the equations, determining which are modified for the DyM-Solver and then implementing your own equations in small steps.

And a floating point exception can be pretty much anything.

Thank you for replying. I will see interPhaseChangeDyMFoam.
