When I use `CVODE_BDF` to solve a coupled stiff ODE (a PDE discretized using method of lines) with around ~1000 variables, is it necessary to provide the exact Jacobian or is it sufficient to just pro…

Diffeqs should perhaps updated to use the new `ode_rk45 `. I can take a look at this personally, if you want.
Sorry for the initial blank issue, I hit enter by accident while drafting this 😕 .

Hello,
I noticed a potential bug with the hasVar() method for level 1 nodes. Here is a code snipped where hasVar() on level 1 returns false but if I transform the same node to a level 0 node and che…

Hi there - this library is very impressive and I'd love to start experimenting with using it within the context of robotics simulation.
Step one for us is looking at getting a stable kinematics sol…
