Parameters to UFL

Question

I'm using ffc to generate .h file from a .ufl, in such a way that I can later include it into DOLFIN C++. I'd like to know if it is possible to pass some parameters to a .ufl file, for example the kind of the Finite Element I want to use (lagrange, RT, DG, ...). If it is not possible, can I "split" the different parts which compose a .ufl file ? For example 1 file for the element I use, 1 for the function and 1 for the variational form and then include all the three .h files into the .cpp files

Comments

To the second question: you can't define form (and generate its code) without element. Maybe you can use import statements to scatter complete UFL code across different files.

Answer 1

You cannot 'pass' parameters to a file (this isn't a UFL restriction, but general programming).

You could write a template-like file and fill in the arguments using some Python code. How to do this is a Python question rather than a FEniCS question.

Ok thanks.
I was a little bit confused because we can compile the .ufl file, and so I was thinking to something like argc and argv in a c++ code, but as you said it is just a file and there isn't anything like a main or something.
Thanks for your help
