Hi all,
I want to solve a poisson equation
ΔD = v
The Laplacian Δ is usually a symmetric positive-semidefinite matrix. Since your documentation of the sparse Cholesky decomposition says

Dear authors,
I have been working with the code provided in this repository and have some concerns related to the methods and claims presented in the associated paper. Here are the specific issues …

Hello, I'm trying to recover the pressure field from a known fluid velocity field using the pressure Poisson equation.
I'm able to compute spatial derivatives of the velocity vector components. I kn…

### Describe new/missing feature
It is known that the Poisson equation has infinite solutions when the boundary conditions like pure neuman are considered. In the Legacy DOLFIN, we use the Lagrange M…

Hello Ehsan,
I changed the u_exit() and the f_exit() in the hp-vpinn-poission-1d.py with the same equation in the paper as:
```
def u_ext(x):
utemp = 0.1 * np.sin(5 * np.pi * x) + np.e…

In the context of solving the Poisson equation one needs to identify the null frequency as a particular case. For now the user has to assume the null frequency is on the first position of the fourier …
