## Main Question or Discussion Point

Dear All,

What type of packages exists out there to the solution of the ODE equations in engineering especially for the M*X''+C*X'+K*X = F ; 2nd order equation, where none of the variables denoted as M, C, K and F are function of the time and are mass, damping, stiffness and force matrices, repsectively ?

Bear in mind that I've all the fore-mentioned entities as matrix in hand, so how am I supposed to proceede further to find the solution of the given equation. Any pseudo example will be appreciated ?

Any suggestion on what type of external packages can I use for the solution techniques, preferably in Fortran?

Regards,
