Hi, Taylor.
I'm trying to do my time domain analyses using point masses now instead of the inertia matrix, as the point masses improved my modal analyses (as per https://discourse.julialang.org/t/ann…

Hi, everyone,
I'm studying the rotor dynamic with ANSYS and ROSS. I recently made a very simple benchmark test to compare the result of natural frequency of a shaft-beam (without any constrain or l…

Hi @Sidaty1 and @jnbrunet,
For this project, I created a ```FEniCS-features``` branch where you should be able to checkout and compile (hopefully).
All the concerning files are in the directory ``…

I tried to get stiffness matrix with a method of "FormLinearSystem( ... )".
I thought A matrix of linear system without constraint is stiffness matrix.
However, acquired A matrix was same size from …

Hi,
I have a minor question. Is it possible to change the way how unknows are indexed? Currently, the stiffness matrix is indexed as:
N1_x N2_x ... Nn_x N1_y N2_y ... Nn_y.
Is it possible to ch…

I'm trying to calculate the RAO for a mesh. Is there a way to do this without inputting the added mass and hydrostatic coefficient matrices?
In the cookbook example in the documentation the RAO is c…
