Morning all,
I have been struggling with modelling a small WEC for a long time. It takes on the shape of a tapered cylinder at the bottom and top, and consistently causes a singularity in the WEC-S…

I was comparing some results (CBAR and CBUSH only) against NX-NASTRAN and found issues with non-null length CBUSH. Checking `EMG/EMG3/BUSH.f90 (is it the good file?) we can indeed see that CBUSH stiff…

Hi @adtzlr
Thanks for open-sourcing `felupe`. Looks great. I have used both FEniCS and `scikit-fem` and completely agree with you on native-installation of FEniCS on Windows (I use it mostly via D…

Hi,
I am new to Apollo and have several questions about the dynamic models used in the LQR controller. It origins from that I find the lines in lat_controller.cc are different from what is said in th…

Hi,
I am putting together an example for incompressible hyperelasticity (u-p formulation) by taking motivation from hyperelasticity and incompressible elasticity examples.
I had a small question…

For the first time, I'm looking at scikit-fem in a serious manner. Diving into it, I notice that the common way the "apply" Dirichlet conditions is to eliminate the respective entries from the matrix/…

Perhaps this is an obvious question, but how does WEC-Sim calculate buoyancy forces? Does it use the hydrostatic stiffness matrix from the BEM (linearized about the specified draft), or does WEC-Sim u…

In the case of solving a time-dependent linear problem, one only assembles once and therefore, only needs to modify the stiffness matrix once. Currently, the possible workaround is to copy A in each t…
