Hi ;
I want to solve forced vibration problem with ODE45. But mass, stiffness, damping matrix are 14*14 and force matrix depends on time and multiple lines have time-dependent forces value.it's been over an hour and still I couldnt see time-displacement graph :( What should I do?

Is your problem stiff? Maybe you need to use a stiff solver.
