Hello,

If I want to refine the mesh to simulate melting (solid to liquid phase) on the attached powder bed mesh, do I use dynamicMeshDict? I'm assuming this is the mesh tool that will allow me to add/delete cells to account for the melting phenomenon.

Here's what I have, but when I run my simulation, nothing changes in the mesh. Is there some command I am supposed to input before I run my simulation?

I'm using OpenFOAM-v1812 and using the icoReactingMultiphaseInterFoam solver. As I understand it, with v1812, dynamic mesh capabilities are built into the solvers. Please correct me if I'm wrong!

********************
dynamicFvMesh dynamicRefineFvMesh;

// How often to refine
refineInterval 1;

// Field to be refinement on
field alpha.solid;

// Refine field inbetween lower..upper
lowerRefineLevel 0.001;
upperRefineLevel 0.999;

// If value < unrefineLevel unrefine
unrefineLevel 10;

// Have slower than 2:1 refinement
nBufferLayers 1;

// Refine cells only up to maxRefinement levels
maxRefinement 2;

// Stop refinement if maxCells reached
maxCells 1500000;

// Flux field and corresponding velocity field. Fluxes on changed
// faces get recalculated by interpolating the velocity. Use 'none'
// on surfaceScalarFields that do not need to be reinterpolated.
correctFluxes
(
phi
U
);

// Write the refinement level as a volScalarField
dumpLevel true;

Any help would be much appreciated!
Thanks!
