Hi @j-fu!
As of this morning's release, DifferentiationInterface is starting to look like a solid replacement for SparseDiffTools in the realm of sparse Jacobians and Hessians. Would you be intereste…

Hi,
I'm currently trying to use DeepXDE to solve the Black-Scholes equation for one space dimension and then higher ones after that. It is as follows:
**Black-Scholes Equation**
$$\frac{\partial …

## Question
I would like to plot the Jacobian matrix at a given time step for a system of PDEs. What order are variables/equations registered in? For instance, if I have three variables V1, V2 and V3…

1. Could we express ODEs in Funsor and then solve them via (approximate) numerical integration methods?
2. Could we express PDEs in Funsor and then solve them via (approximate) finite element methods…

After reviewing the "Getting Started" notebooks, the next step is to restructure the "Creating Models" ones. The idea is to have a cohesive set of notebooks that build progressively more complex model…

** Does MOL support BCs including Algebraic Equations❓**
I'm trying to solve a "realistic"/"engineering" type PDE system with MOL. Most (every?) example I have seen of the use of MOL just contains …

I was just wondering what the progress is for the development of PDEs in the context of formalizing partial derivatives, finite difference methods, and well-posedness for PDEs. Basically a good suppor…

Going forward, things like constitutive laws and PDEs are not needed by everybody, and therefore it should not be necessary to compile them if I don't use them. How do we want to handle these in the f…

species with D=0 are subject to variable reduction in PDEs and then not recognized as variables for post processing stats.
