Hello guys!

In order to test whether SU2 is installed correctly, I ran the test case RAE-2822 and this gave some strange behavior... However the first optimization try gives the good results:
NIT FC OBJFUN GNORM
1 1 1.345e-5 3e-3
2 2 1.1214e-5 1e-3
3 3 1.113e-5 7e-4

However when I copied the folder and run it again, it will give the following result:
NIT FC OBJFUN GNORM
1 1 1.345e-5 1.14e-3
2 4 1.1209e-5 3.7e-3
3 8 1.116e-5 3.22e-3

Furthermore I saw that the DV_values in the first try are changing randomly. However the third/fourth/etc. run are just divided by 2 each time...
I hope somebody can indicate the source of this problem and might have a suggestion to overcome this problem
Thanks in advance!

Kind regards,

Floris
