Fixed size numerical structures (vectors and matrices) are critical to extracting the maximum performance out of the code by providing as much information as possible to the optimiser. Depending on e…

### Problem Description
At present the only two DFT's available for the symmetric group algebra are the seminormal basis and modular DFT. Neither of these are unitary transformations.

I’m trying to solve a simoleODE:
u’’’’=1
With BCs u(0)=u(1)=0 and u’’(0)=u’’(1)=0
My code:
import firedrake as fd
import numpy as np
import matplotlib.pyplot as plt
N=20
mesh=fd.UnitInte…

Hi all,
it would be possible letting PrusaSlicer export in STL (or STEP format) the results of the slicing procedure?
PE is able to generate complex structures, I am thinking above all of the infi…

An important consideration for PDE-constrained optimisation methods is "mesh dependence".
The standard approach in `firedrake_adjoint` is to extract the vector data that underlies the control field…

Dear all
I'm trying to use BoomerAMG as a preconditioner to solve a 3D laplace problem which is assembled by a finite element code.
I have the particular problem, that a small number of the basis …

Calculating Green's function's for interacting clusters with off-diagonal hopping we run into strange behavior of CTHYB. For a hybridization function without off-diagonal elements the off-diagonal ele…
