We observed a remarkable difference in stiffness matrix between Caribou and FEniCS.
@Ziemnono provides Gauss points for FEniCS.

Consider the ScalableTestSuite.Elementary.SimpleODE.ScaledExperiments.CascadedFirstOrder_N_XXX models. They contain a cascaded connection of first-order linear low-pass systems, so the Jacobian is bi-…

A core part of the Mpfa and Mpsa discretizations is the construction of basis functions on subcells see ([review paper](https://doi.org/10.1007/978-3-030-69363-3_4)) for details. This is implemented a…

When I calculate the blade section characteristics with bpe and precomb respectively, the results differ greatly. Why? In addition, when running bpe, polyfitdata will appear Mat does not exist. What t…

Hi,
may I sincerely ask in MFEM, is there any simple call from ParGridFunction to a MFEM::Vector ?
Thanks

Hi!
I am currently using MFEM to solve structural problems accounting for geometric nonlinearities. In order to achieve that, I have defined a custom `NonlinearFormIntegrator`, in which I have modi…

Sorry if this is dumb, but can you please tell me the definition of the stiffness matrix the code requires? I tried using this one: https://link.springer.com/content/pdf/bbm%3A978-3-319-56493-7%2F1.pd…
