@ Doug : I have uploaded the file again and also have pasted the equations for your convenience.

@ John: Actually, the starting equations namely, eq1 and eq2 are the functions returned by pdsolve (symbolically solved). And the original equation for that is this ...

eq0 := diff(CFr(x, t), t)-(diff(DC*(diff(CFr(x, t), x)), x)) = 0

where DC is a constant and assumed to be equal to 1 for simpler calculation steps.

When you solve the above equation symbolically you will get a solution with 2 arbitrary functions _F1 (second order diff equation) and _F2 (first order diff equation). And eq1 and eq2 are _F1 and _F2 respectively.

Could you please give it an another try?

Thank you.
