Hi Patrick
I am trying to calculate the first order sensitivity w.r.t. to all the three kinetic parameters for the Robertson Equations using `diffrax`. I am using the stiff ODE example provided [he…

I am currently implementing a physically constrained neural ordinary differential equation. The application is reaction kinetics so you already know it's going to be a very stiff system. The governing…

I am currently working on some tasks on the derivation of chemical reaction equations and I have found that torchdiffeq does not seem to provide support for some solvers such as ode23tb and ode23s in …

Hi,
I am modifying the latest version of the CLASS to incorporate massive neutrino self-interaction. I implemented a new tight coupling approximation(tca) for the ncdm species.
My code is workin…

Hello,
is it possible to use user defined linear and non-linear solvers for stiff systems, especially sparse solvers? I would like to use odeint for solving partial differential equations. Hence, t…

Currently trusses are hardcoded and the stiffness is added to the stiffness matrix directly. It would be nice to have FEniCSX do this work.
FEniCSX currently does not support mixed meshes and theref…

In the contact mechanics equations, we currently compare tractions to c_num times (increments of) displacement jumps. C_num is by default computed as
c_num = shear modulus / (solid.residual_aperture…

In SimplyP v0.3 we replaced reach length with effective reach length in the reach flow equations. The intention was that the effective reach length should represent the average distance travelled by w…
