Numerical schemes available in OF 2.x
 
Hi guys! Is there a page where I can find all or almost all the numerical schemes available in OF 2.x? I can only find posts with previous versions of OF but also the syntax has been changed through the new versions. I'd really need it because I'm troubling with a very sensitive simulation which doesn't converge.

Any help is REALLY appreciated.

Cheers
Simone

Just in case, this is a good starting point: http://www.openfoam.org/docs/user/fv...#x20-1070004.4

Hi Danvica,
thank you for your answer..actually I've already read that page but I'm looking for something more detailed, especially about ALL the schemes available. Notice that for gradSchemes just a little of them are explained in the page that you suggest but actually there are many more availlable..The point is that I can't find the usage of each of them..

I'm not sure but I don't think there's a single document explaining all, i doubt that for many it exist even a small doc.
Did you try in the past workshop papers ? You can find lots of interesting info here and there...

Where can I find them? On this forum?

Hi Simone,
You can give the name of a scheme that doesn’t exist and OpenFOAM will give an error message with all available schemes. At least you will know the name of the schemes.
Regards,
Paulo

Hi Paulo thanks for your anwer, I've already experienced what you're saying. I'm really starting to think that what I'm looking for doesn't exist..

I've never seen a comprehensive detailed explanation of all the numerical schemes, although you may be able to piece together something from the c++ documentation. Before going down that rabbit hole, I'd suggest verifying your mesh and boundary conditions are good; most stability issues usually stem from those two in my experience.

Hi,

there was the desire to work on s.th you are looking for
http://www.cfd-online.com/Forums/openfoam/69068-foam-documentation-project-shut-down.html but this attempt was stopped!

i guess the mentioned workshop http://www.openfoamworkshop.org/2012/OFW7_Program.html
http://openfoam-extend.sourceforge.n...W7_Former.html

OF-related PHD thesises http://powerlab.fsb.hr/ped/kturbo/OpenFOAM/docs/

there is also http://www.tfd.chalmers.se/~hani/kurser/OS_CFD/

Hi,
I'm sorry not be able to help with solvers documents.

Some weeks ago I found a post containing the direct links to all past Workshops papers... but I don't remember where and whom :(

The link http://www.openfoamworkshop.org/2012/OFW7_Former.html is pointing to "Page Not Found"...

Do you know others links ?
