joescor2 is on a distinguished road

Im working with CHT and with an important computational domain.

The thing is tha i need a refinement of 0.5 microns in the combustion chamber walls for an experiment that we are carring out with a lumped model.

My base grid is of 3mm so i need an embedding scale of 2.585 but converge doesnt recognize this value (at leasr in V2.3 and V2.4). The easiest way is to reduce the base grid to 2mm, so i could use an embedding scale of 2. However this would increase considerably the computational time and we dont have such a long time to get the results.

Can i to set the value 2.585 in the embedding scale somehow?

I would appreciate the help.

Best regards,
Johan E.
