Hi,

If you define a passive scalar, e.g. scalar(x) and it is to be calculated in any subroutine via a variable 'y'. How do you define that you want the value of y to be scalar(x). So after doing this you can then post process it?

I'll appreciate any help, thanks

You can define the scalar value e.g. in the sorsca.f subroutine.

You can write

if(IS.EQ.xx)then

where xx is the defined passive scalar.

Then you can write

S1P=Large_number(like 1E+25) times "y"

S2P=Large_number

After this, the scalar xx has the value "y".

Not sure I follow Ossi's example. I would use the subroutine "scalfn". In scalfn, do the following;

if (is.eq.x) then C where x is the scalar number phi = y end if

This routine is called for every cell and will put the value "y" into scalar "x", which can be post processed in prostar by; load,, getc conc x
