Just curious, how is Stiff3 compared with DVODE by Byrne and Thompson? > [@Has anyone used DVODE and is it good?](https://fortran-lang.discourse.group/t/has-anyone-used-dvode-and-is-it-good/2281/11): > > Thank you very much for the message @nicholaswogan , true, strangely, the original link does not work any more. Fortunately, I have downloaded their whole website (the latest version) of dvode before. Now I pushed it to a new gitlab repo, you could download it from the link below, In the folder VODE\_F90 Support Page , double click index.html, then you should see the whole original website, and you can download all the corresponding files locally. Hope that helps slight_smile DVODE can solve stiff problem too. --- _[View the full topic](https://fortran-lang.discourse.group/t/stiff3-adaptive-solver-for-stiff-systems-of-differential-equations/1687)._
