Hi all,

I am trying to do a heat transfer between 2 different solids. One of which has anisotropic behavior.
I have read a few threads -directionalKSolidThermo syntax.

I believe we can add the thermal conductivities of the Anisotropic material in different directions to the thermophysical properties file of that material.

Please advise a direction to begin with.

Any leads would be much appreciated. Thanks.

Hello,

There might be different options depending on the OpenFOAM development branch.
From what I remember:

In the OpenCFD branch (openfoam.com) since OpenFOAM-v2206: New tabulated anisotropic thermal conductivity solid transport

In the OpenFOAM foundation branch (openfoam.org) since OpenFOAM-11:

New solidThermophysicalTransportModel provides a thermophysical transport model for solids, supporting anisotropic thermal conductivity [ commit cdaaa6 ].
Corrected heat flux calculations at boundaries with anisotropic thermal conductivity [ commit 01d2c6 ].
Added optional boundaryAligned switch for anisotropic thermal conductivity κ to force a principal direction of κ to align with the solid boundary [ commit d26e0f ].

Check the transport modelling section of the release notes: https://openfoam.org/release/11/

I don't know if this matches your needs, but it's probably worth checking.
I hope this helps,

Yann
