I want to simulate a model with 2,418,880 discretization points under quasi-static conditions. For this purpose I use the NOX solver. When I run the simulation the tangent matrix is s…

One of the techniques for imposing Dirichlet conditions in the finite element method is Lagrange multipliers [TODO: add references]. This has been mentioned in a few previous issues [TODO: ditto].

WEC-Sim currently assumes that the hydrostatic stiffness matrix has values only on one side of the diagonal. This is true for WAMIT but not for AQWA (not sure about NEMOH). We should change it so that…

Hi,
First of all, your library seems to be very interesting. But here a quick how-to question :
If I want to get the stiffness matrix of the following materials :
wood A 10mm thick (without fi…

I noticed strange results when I meshed a rectangular panel 10 units wide by 20 units tall with a mesh size of 0.5 units. If I change the mesh size to be larger or smaller, or if I change the panel si…

In some cases, LinearSolverApplication returns singular matrix while the same example can be solved by ExternalSolverApplication.
For linear solver, I am using:

The ability to add a spring support directly to a node rather than creating a new spring element might be helpful to many users.
The DefineSupport function could be setup to somehow take true, fals…
