Hi, here I would like to discuss the paper structure. Here is what I propose
1. Introduction
1. Problem formulation and contributions
Given a flexible robot with nonlinear d…

I have been successfully solving a system of 123 ODE’s for the past few month using Julia. I have tried a number of solvers (see some commented out code below). The Tsit5 (fifth order Runge Kutta) gen…

The $\varepsilon$_-embedding method_ is a tool that can be used to get insights into the behavior of numerical methods when applied to stiff ODEs and DAEs. Assume we have a stiff system of ODEs of the…

Hi, has anyone noticed that RxODE and Berkeley gave different simulation results? Apparently, they use different stiff ode solvers. RxODE uses LSODA, and Berkeley uses Rosenbrock. I also noticed that …

I'm not sure this branch is doing anything:

Hi,
I have an ODE system with 42 equations and 101 parameters. Solving this model with
**solve_ivp(model, time_span, y0, args, dense_output=True, data_point=250, rtol=1e-6, atol=1e-9)** cost aro…

Brilliant project! So, do you have a clear answer now? I'm using RNN to predict continuous time series on tensorflow. The desired ouput of squared waves is more precisely imitated by MATLAB rather tha…

I am interested in experimenting in adding multigrid preconditioners to existing codes I have written. I am attempting to do so using the MGMatrixBlockVector functionality in the MeshWorker framework…

I am interested in using this in a more academic case, and in previous discussions it sounds like that's a development target. So I was wondering if there could be examples showing how to do it. Essen…

@devmotion does the Enright DDE test problem set have some good stiff problems?
