Hi developers and users, I completed an input script, which is a 1st-order time dependent PDE including 2 equations and 2 variables. Then I generated this error when link the program. I have checked my codes with ex9 & ex11 a couple of times, but still can't get the code work.
The problem may lie in the 'exact_solution' function, I have define it before main code as "Real exact_solution (const Real x,const Real y,const Real t);" did I miss some head files? Thanks!
