Did you change the Makefile config (Parallel mode flag AND compiler) and recompile the entire code?
Hi Jijo,
you better work with global coordinates, like in the examples cylinder2d and cylinder3d it is done for the pressure drop. You can get the cubpoid number by methods provided by the cuboidGeometry2d class. Note that you have to differ betrween local and global coordinates as well as local and global cuboidNumbers.

MathiasWe would be happy to welcome you in the OpenLB consortium worinmg on that open problem together since it is also in our interest! Best Mathias
FORCE is basically for the surface tension and EXTERNAL_FORCE is for any other forceslike gravity, magnatic,..
Dear Lasya,
without nowing details I cannot really help you. Next week, the spring school starts. That would be a perfect chance to get that working together..

MathiasIn about a week we have our next spring school oin Greenwich — please consider coming. That is a good start into LBM.
No, not yet — within a project we could implement such a model.
Its not possible to answer it without knowing the details. E-mail me to set up a common project..
Dear Alexime,
a good start is to look at our examples, e.g. the cylinder 2d/3d cases and start form there. Both are benchmarks, i.e. they have been validated by comparing them to other results.

MathiasDear Mike,
maybe you find mor information looking for publications of Jonas Latt or Orestis Malaspinas on that topic.

MathiasYou could also look in the previous paper, I mean the ones before ours.. We also did compare our results to a non-LBM approach. So we have some evidence..
I guess it is a parameter to conrol stability on the cost of accuracy.
That is what pressureBC is doing.
1/ I would use a Smagorisky model in combination with BGK. For the free flow, I would set a Pressure BC (=Direchlet Zero for Pressure, Neumann Zero for Velocity).
Dear Anas,
please, have a look at our other examples on thermal flows. There might be a similar situation which you can copy paste from.
