I am performing free-free modal analysis on a floating structure, and I'm looking for a way to determine significant vibration modes (without forced response simulations).
In my investigation, I came across the following...
Hi all,
I have this doubt when it comes to estimating a rigid body rotational stiffness from a eigen frequencies analysis.
At first it seemed straightforward to me, using the fundamental dynamics equation w_n = sqrt(K/M), where w_n = f_n · 2 · PI
However, I seem to be reaching a unit...
Hi all,
I am doing some SOL103 analysis on certain subsystems of a floating structure, and I'm exploring different approaches at representing the whole structure's added mass.
One of my approaches is to simply represent the floating structure as a rigid body, using a CONM2 element.
This way...
I have some pressure data coming from a CFD analysis.
After reading through the multiple posts here and watching videos on youtube, I was able to mostly apply the pressures to my model in a coherent way.
I'm having trouble regarding a specific area of the structure, however.
In the CFD...
