I don't know if this is the right place. I have checked other open issues, but I would like to add an adaptive stepper to the list of possible timesteppers....
I had in mind creating a solver that uses the Dormand–Prince (RKDP - proposed tag) method, comparing the 4th-order solution to the 5th-order solution to determine whether the step size...
I have coded the embedded schemes listed in Table 8 of the [Kennedy & Carpenter paper]. I have done some light testing, but I was wondering if there are any...
The scheme with adaptivity passes the 1D heat equation test. I have forked the repo and created a separate branch to work on the adaptive stepper. I will add more...
Discussing the code would help integrate it properly into Dedalus.
Pull request has been opened as 'adaptive stepper' to discuss and review code.
I want to find some lower-order embedded methods that would increase the speed of these solvers. The Kennedy and Carpenter schemes are 4th and 5th-order; ideally, I should find a...
Hi @bpbrown and @kburns, any suggestions for how this can be improved?
