Hi there,
I'm solving the heat equation using finite difference method, in which an nonlinear solver is needed.
I found kinsol will be broken after several steps. The error is as follows.

Hello,
Does gsl-shell for Windows come with the full gnu scientific library for accessing functions not yet implemented in the shell itself, but could still be accessed through the FFI (such as BDF…

Hi @iBatistic,
Thanks for pushing the hyper-elastic Cook's membrane case.
It seems to work for me now with OF.com when using the SNES solver; see the case and scripts I pushed at https://github.…

Using the "production" branch of OpenRAVE I get the following error relatively fast after invoking ikfast for a robot model. I updated from an older version, which does not exhibit the error but appea…

First of all, many thanks for building this library. It is very useful and your hard work and effort is very much appreciated.
I have a Pressure Poisson Equation with pure Neumann boundary conditio…

Often, we need some estimates of the wave speeds, e.g.
- for CFL-based time step control
- for numerical fluxes like local Lax-Friedrichs, Harten-Lax-van Leer
In principle, multiple estimate …

Reviewer `#3` (Remarks to the Author):
In Table 6, why are the computational domains chosen as cubics for all proteins for APBS? It is unfair for APBS in terms of efficiency.
In Table 7, solvat…

Okay I'm trying to solve this particular set of ODEs and I'm unable to find out where I'm going wrong.
```python3
import sympy as sp
R = sp.Function('R')
F = sp.Function('F')
t = sp.var('…

>>> solveset(sqrt(x)-I, domain=S.Reals)
EmptySet

It seems if domain is S.Reals, intermediat…

Hello, it's been a while since I've been trying this package before and I'm happy to try it again, now that I see that there are many new solvers etc.
The issue I'm facing is the following (rather …
