Hi,

I'm trying to perform finite element analysis on a cantilever beam under a sinusoidal load using MATLAB.

I first used ANSYS for transient analysis to obtain data (Mass, Stiffness matrix, deformation, acceleration of each node/No damping) for a duration from 0 to 1 second with a time step of 0.02 seconds. Then, using the equation f = mx'' + kx, I calculated the force matrix in reverse. After that, I interpolated the discretized forces from 0 to 1 second and used ode45 to recalculate the deformation and acceleration of each node. However, the values I obtained are too large.(almost 10^100)

 

Is this approach correct? If not, how can I use data obtained from ANSYS to perform FEA in MATLAB?

Hi,

Please refer to following course titled: 'Finite Element Analysis with MATLAB and ANSYS'  on Udemy which may beof help to you.
