Hello,
I have a time-dependent model that I solve using TSSolve.
And I am trying to adaptively change the step size (dt).
I found that there are some TSAdapt schemes already available.
I have tried TSADAPTBASIC and TSADAPTCFL.
The former runs without any problems, whereas the latter yields th

`MatAssembly*()` does not say it is necessary for `MatSetValue()`. And the man
page of `MatSetValue()` does not say it is a must to c
