[Other] Import fields to new mesh

DGW · December 31, 2015, 11:33

Hello everyone !

I am currently running a simulation using the rhoCentralFoam solver and everything is going relatively well.
The problem is that there are areas of my mesh I would like to refine by, for example, changing the number of cells of some of the hexaedras of my blockMeshDict, but WITHOUT having to restart my sim from 0 (and lose the dozens of hours of computing time I used). So basically, make a "new" mesh from the same geometry but keep the existing solution solution from the "old" mesh.

Is it possible ? If so, how ?

Thank you for your help!

Hi DGW,
You can use the mapFields utility as described in item 2.1.5 of the User Guide.
Happy New Year!
