Dear all, I have a function temp(p,h), which returns temperature dependent on pressure and enthalpy. I insert UFL representations of p and h into temp(,). Then I do some +,-,*,/ operations and afterwards want something like python int(,). How do I do this in valid UFL syntax? And finally I want to access an array with the vector of values I got, and save the values I get back to the UFL form. Henrik -- Dipl.-Math.
