Mass Matrix,Stiffness Matrix,Damping matrix description

Post by Shayor »

I needed to know where the values of normalized mass and normalized stiffness came from in the tutorial for FSI in the documentation?Have these values been defined previously?Could anyone help me in that?

Hello,

Are you referring to the tutorial on the website (the old v2.0 tutorial), or another example we use in some courses (which might be added in a future "open test cases" repository we will provide) ?

In any case, if the information is not found in the tutorial description, I am afraid I do not have anything better to provide.
You may check if the values are in a range which seem logical compared to "standard" definitions (at least, that is probably what I would do), but I have no better suggestion.

Best regards,

Yvan
