[FLASH-BUGS] assymetrie in hydro flash 2.1 and 2.3

[Markus Gross]

Hi again!

I have now ported an example to 2.3 and I get similarly wrong results. The 
setup is attached. There are as well some images in the tar file which 
hopefully help to illustrate my problem. Where scalar values are indicated in 
the images, don't be surprised, all values occur twice, this is a feature of 
the vis-program. These are noniterpolated values though and hence you should 
be able to reproduce them with any tool - all images are generated from the 
10th plotfile.

image1.gif - the whole simulation domain, three planes for visualization 
(xy,xz,yz) 


The xy plane is the one where it goes wrong, shown in image2.gif - it looks 
fairly symmetric, but it is not.. (btw. this plane is one cell away from the 
boundary condition)

image4.gif-image9.gif show the scalar values around the colored region in 
anticlockwise order. You'll see that there is symmetry with respect to 
top-bottom left-right, but the values on the right side are not the same 
compared with the respective positins along top or bottom.


I hope I did not miss anything vital in my hack style port to 2.3 ...


I am looking forward to hearing from you and will investigate further.

Regards,

Markus
