I am new to OpenFoam and simulating a simple case of buoyancy-driven circulation in a flask (see image). The "lid" of the flask, actually a liquid-below-air interface and here treated as a free slip boundary, was held at T=-0.01 K; the rest of the flask wall was held at T=0 K. The solution, computed using buoyantBoussinesqSimpleFoam, is shown here at 5600 iterations and although the residuals have ceased to decrease this cannot be regarded as being the (sought for) steady state, which should be axially symmetric.

Now to the problem. The above setup is only a first pass. I would like to have the flexibility to impose a non-uniform initial field of temperature, and to vary the temperature boundary condition within patches. I understand that this is (or has been) possible using groovyBC and funkySetFields, and I have the impression that these have been subsumed under swak4Foam. I've attempted to install the latter, but I'm stuck. I may have an incompatibility, and would appreciate any guidance.

I'm presently running OpenFoam2006 (sourced from ESI) under openSuSe Leap 15.2 on a DellXPS15 (I also have OpenFoam Version 8 running under Ubuntu 20.04 on the same dual-boot Dell XPS15; the reason for installing OpenFoam2006 is that it provides buoyantBoussinesqSimpleFoam). My immediate problem is that I don't know whether swak4Foam is compatible with either of my installations, nor, if it is, which of the various "Unofficial OpenFOAM" wikis would be a reliable guide for installation, since these wikis refer to OpenFoam versions with numbers like OFv1.5 (and perhaps no later than OFv3.2).

Since ESI version 1912, expressions based off Swak4Foam have been allowed: https://www.openfoam.com/releases/op...processing.php

Great! Thanks Chris... John.
