conjugateHeatFoam in OF 2.2.x

ala · November 21, 2013, 02:46

Dear all,

i am interested in use of block (coupled) matrix libraries of OpenFOAM.
So, i 've started with region coupling example.
I have already seen/read Hrvoje Jasaks and Klas Jaretegs slides.
I take a look af conjugateHeatFoam OF 1.6-ext and conjugateCavity example.
The class coupledFvScalarMatrix is not given in OF 2.*.
I think i can use block matrix classes to implement this.
As nice exercise for use of block matrix classes in OF.
Does it make sense?

Any hints are welcome.

Dear all,
i took a look at version 1.6.x-ext, and conjugateHeatFoam and blockCoupledScalarTransportFoam solvers.
So ... .
The 2.2 version of class BlockLduMatrix ist LduMatrix (not lduMatrix).
What happened with CoeffField and VectorN class?

Dear all,

in the release announcementOF v.2.2.0 is implicit region coupling mentioned.
I try to use this boundary condition, but i have problems.
Any ideas?
Some tutorials?
Someone who also want to use it?

cite:
Implicit Region Coupling

For multi-region cases, such as when modelling conjugate heat transfer between multiple fluids and solids, the solution of the energy system when using a segregated approach may require many iterations to converge. This is partly due to the explicit treatment of the thermal boundaries coupling the regions.
A new framework for the implicit solution of coupled thermal boundaries has been implemented, allowing a closer coupling between the solid and fluid regions. From a user perspective, the only change necessary is to employ a new type of boundary condition. Currently, this is still a work-in-progress, and under active development.

can i use this boundary condition (implicit region coupling) with chtMultiRegionFoam solver?
