Hi Derek, Sorry for the late reply.
1. The W-IMEX is used as the base method in TSEIMEX. So TSEIMEX implements 2.4b. 2. Thank you for catching the mismatch. An MR has been submitted to fix this. Hong (Mr.) From: petsc-users <[email protected]> on behalf of Derek Teaney via petsc-users <[email protected]> Date: Wednesday, June 12, 2024 at 10:22 AM To: [email protected] <[email protected]> Subject: [petsc-users] Questions on EIMEX: Dear All, I have a question and a comment on the TSEIMEX scheme in the TS routines. 1/ Looking at the cited reference, I see three schemes there 2. 4b, 2. 4c, 2. 4d . It is not clear which of these is being implemented. 2/ The documentation for ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization. ZjQcmQRYFpfptBannerEnd Dear All, I have a question and a comment on the TSEIMEX scheme in the TS routines. 1/ Looking at the cited reference, I see three schemes there 2.4b, 2.4c, 2.4d . It is not clear which of these is being implemented. 2/ The documentation for EIMEX mixes up F(u, udot ) and G(u) relative to the users manual. This may have been done on purpose, to conform with the Constantinescu ref., but a perhaps a comment is in order.
