3.6vs3.5 HOCS convergence
 
Hello Everybody,

I can't get convergence with any of the higher order convection schemes with v3.6 in low-speed flows around buildings. Is there a problem with the code or is it just me?

I have relaxation tightened appropriately and v3.5 will converge perfectly with these parameters. I just can't see what is wrong. I would use 3.5 only I need to use some new options in 3.6flair. If anyone is interested, try to converge the (small) library case v407 with HOCS. Please englighten me

Kind Regards

I'd sure like to know the response to that one!

There was a problem in the W-momentum. If you switch off HOS for W1 it should work, however this has been fixed via the first texter raising it as a support issue. If you mail in support we can provide you with a patch.
