[Gfs-users] runtime error with derivatives

[Barak G. <ga...@oc...>]

Hi All,
I am running a simple example (reynolds.gfs, see file attached) to check
the derivative function:
dx("U")
I get a runtime error:
Gfs-MESSAGE **: floating-point exception in user-defined function:
dx("U")

What's wrong?

Many thanks,
Barak
