Hi, I am playing around wit
I am playing around with OpenFoam for quite a while now but I still have my problems when it comes to choosing the "order" and "schemes" for those files.
In general I understand what every entry does and what the influence should be - but lately I ran in trouble with a perfectly working set of files and I could not figure out why.
My question would be if you have any general tips you can give me or even just paste a fvSchemes file you are using.
Right know I try to get a very good result for the drag of a sphere in low Re number area (50 - 200) so far I am using IcoFoam, but I am open for any suggestion to improve my current results.
My current fvSchemes:
My current fvSolutions:
These files worked great for me for Re=200 and Re=150, but on the same mesh and lower Re (50,100) the Drag is too high.
Thanks a lot
Hi Daniel, I would use back
I would use backward or CrankNicholson for ddt, limitedLinearV for convection, and I would tighten the tolerance a little both on p and U.
Thanks for the input I will ru
Thanks for the input I will run a simulation with these settings and will report back - other comments are very welcome.
So, I am running now with t
I am running now with the following modifications:
default CrankNicholson 0.5;
div(phi,U) Gauss limitedLinearV 1.0 phi;
I will report back when I have some results.
did you have a better results with the new settings?
