i have a problem in doing a source code using C programing. I'm doing an equation related to the mass spring system in FDTD. My problem is how to to do the coding for damping . the algorithm is

[d²X/dT²] = 1/m[-b(dX/dT)-kx]

b is the damping constant and k is the spring constant.

Thanks...

 

You have to try Numerical Methods Subject. Its a Maths paper for 3rd Year Engineering Colleges of Tamil Nadu. Using that you can solve Differentiations and Integrations in a simple manner. I will search for a link and If i get it, i will post it in my next reply.. Bye
