I can't get the bi-Laplacian to work in part 1 with the Laplace-Beltrami matrix. (Queried whether the solver successfully factorized the matrix using `solver.info()`; also printed out some coefficient…

Hi, first of all thanks a lot for the nice implementation!
I was wondering if it would be possible to allow the output to be the individual d^2 f / d x_i^2 as well, rather than the version that sums …

Currently, we offer two versions of the Laplace operator - de Rham and Beltrami - for each form and each dimension of delta dual complex.
However, we do not generate Laplacians for simplicial sets. T…

There is a package ManifoldLearning: https://github.com/wildart/ManifoldLearning.jl . Only partially related but we may still want to take a look at what it does.

Hi,
I am trying to solve a Vector-Laplace equation on the sphere using Gridap. I wanted to test the influence of the geometry approximation, reason why I would like to use higher order geometrie…

Hi Stuart,
I wanted to use your code to solve the Helmholtz equation on a cortical mesh. I've downloaded your BrainNetworkModels but haven't figured out how to implement the simulation. Specifically…

Hi,
I am trying to modify the mean [discrete curvature measure](https://github.com/mikedh/trimesh/blob/master/trimesh/curvature.py#L78) method. I am trying to refine the candidates this method uses…
