Determine a way to apply very weak spring to unstable models. In the case the equilibrium state is maintained by the forces (thus requiring no supports), weak springs should be added in the diagonal o…

The issue is that 1D structural elements do not seem to be constructed properly when they not aligned with the x-axis. For example, the 1D bar extension example works fine when it is oriented along t…

Dear yixuan,
Thank you very much for developing the package as a c++ alternative of ARPACK. It helps me a lot.
Currently, I am using SPECTRA to solve the frequency problem in Finite Element Method…

Hi there,
Many thanks for sharing your application first of all, it looks neat!
Now going over to my issue:
I am interested in conversion of my Nemoh results into .Wamit such that I can uploa…

I would like to introduce settlement of a support or, in general, the possibility to choose a nodal displacement. Pratically it rappresents a new load for the model, but it rappresent also a non homog…

I actually just discovered the bending_operator stuff last week. But when I tried using it and set NO_BENDING in a 1D extension example problem, I get an error indicating "property not found for : kap…

Dear Michael (@mhscott ),
The recent introduction of moment releases for elastic beams is very useful, however there must be a bug in the code. The issue is that, for example, for a portal frame, w…
