Dear All,(adsbygoogle = window.adsbygoogle || []).push({});

I'll need your guidance on how to solve the equation generally encountered in engineering equations, which is mainly in that form M*X''(t)+C*X'(t)+K*X(t) = F(t), where M, C, K and F(t) are mass, damp, stiffness and external force matrices respectively. Actually those equation may come in many flavours ranging from the absence of any terms on left or right side. Additionally the solution that we are seeking may not be a function of time (transient) as conversely I've formed above. Generally it's been called Duhamel integral and may have or not inclusion of the eigenvalues, so what I'm asking is introductory info and any suggestion on the good book related to that topic.

Also I'd like to take the suggestion from you for the good programming library e.g. Lapack, Arpack, Slepc, Petsc etc.. which solves the fore mentioned equation with different type of variation of LHS and RHS.

Your comment will be appreciated.
