hi,

is it possible to check if a cell is within a cellzone?

i could basically store a checkId and then loop over all cells within that cellzone and then check if Id of both are equal. but that would take up so much computation time for my domain size.

is there a faster way of doing that?

You could set up a list, one entry per cell, with a 1 if it's in the cellZone and 0 if not. Do this at the start of the run, and then keep the list. For later iterations, then it's just a simple look-up in the list, i.e. ultra fast.

Something as simple as this?

label zonei = mesh.cellZones().whichZone(cellId);


if (zonei < 0)
{
    ...
}

Can also use zoneMap() if that helps.
