I'm trying to solve a system of differential equations. It works fine but Mathematica creates a huge output, which, when shown in full, results in a file size about 100 mb. Using Simplify doesn't work because of a time value problem. Is there another way to use the calculated constants C1 to C12 as variables than open the full output and replacing the arrow operator with an equal sign? Because the huge output really slows down further operations. Or how could I solve the Simplify problem? FullSimplify takes so much time, that I don't think it will work.
I am using version 8 by the way.
Thank you for your help.
