ALPHA location?
 
Where can i set ALPHA variable which Controls weighting of upstream values in advection approximations when IORDER=1, when equal 0.0, is central differencing and when equals 1.0 uses upstream differencing(upwind)

alpha is set in the xput namelist.

of course i know its in the xput namelist, i just want to know how can i change it?
Is it for example in the NUMERICS tab or...??

It's not in the GUI - you change it directly in the input file.
