Dear All

How are you ?all . long time not login this community.

Please guide me to solve System of Differential Equation in Mathcad as Example below

Mx''+Kx=p(t) harmonic force

If this example is error please feel free to change the purpose is how to solve in Mathcad Prime

Thank u

You have to provide initial conditions for x1 and x2 and their first derivatives.

Success!

Dear Luc

I got real example but I don't clear to choose initial condition and not clear with Differential Equ. System (poor me Math), I wanna you help to solve the solution of this system by symbolic solution

I have (attachment file)

MX"+KX=F(t)

Big thank Luc

Your problem is too big for Prime, and lacks data:

- Prime 8 is crunching for almost 2 hours on the solution and hasn't found it yet.

- You need to supply the initial conditions for x1 through x14 and their derivatives.

Thank Luc

I think if we solve as symbolic may not need initial condition,
