Hi Jens and Daniel, Thank you. It was exactly what I was looking for.

List -> Times Protect[Power] and FortranForm[a*b^4*Sin[w^2]] gives a*(b*b*b*b)*Sin(w*w) Regards Jens Reza Farrahi Moghaddam wrote: > Hello, > > I am using Dolfin/FFC for solving finite element problems. I want to use Mathematica for generating the linear and bilinear terms of the weak equation. After computing the terms, I use the "InputForm", and then give the results to FFC compiler. The problem is that FFC does not accept "power" function. Therefore, terms such as "a^2" must be written as "a*a". Because there are many terms in the weak form of my problem, manual conversion of power terms takes a long time (and probably is subject to errors). > > Is there any way to disable "power" function, or stop "times" function to be simplified in the "power" form? > > Any other solution? > > Thanks, > Reza > >
