I need to subdivide the solid regions into volumes with different isotropic conductivities.(kappa) (already at 13 regions with a potential 70 subregions) I was looking at scalarsemimplicitsource or vectorsemimplicitsource.
anyone done it this way?
is there another approach?

regards Derek

Hi Derek,
It probably depends a bit on what you are trying to achieve. However, why not just create discrete regions in your geometry, mesh it, and assign properties as normal?
Kind regards,
Peter

80 discrete Regions? with all the files in Const and system to add and modify?
13 is bad enough

Hello,

Well, the meshing is straightforward and a simple script can take care the constant files and BCs. :-) Alternatively, you could modify and roll your own solidThermo library with kappa as a field variable (i.e., one that you could set per cell in the mesh).

If it were me, I would just take an hour and do the former, but then that's the beauty of open source - lots of ways to solve problems!

Good luck!
Peter

akidess will become famous soon enough
kappa is a volScalarField read from an input file, right? Then you can work with topoSet and setFields to define it.
