Major Features
New Features and Enhancements
The functions CVodeGetUserDataB and IDAGetUserDataB were added to CVODES
and IDAS, respectively.
Bug Fixes
On the initial time step with a user-supplied initial step size, ARKODE and
CVODE(S) will now return ARK_TOO_CLOSE or CV_TOO_CLOSE, respectively,
when the requested output time is the same as the initial time (or within
numerical roundoff of the initial time). Before a TOO_CLOSE error would only
be returned when internally estimating the initial step size. In IDA(S), added a
IDA_TOO_CLOSE return value for when the initial and output time are too
close. Previously, IDA(S) would return IDA_ILL_INPUT.
Fixed a bug in ARKODE, CVODE(S), and IDA(S) where the linear solver counters were not reinitialized until the next call to advance the system. As such, non-zero linear solver statistics could be returned if retrieving or printing linear solver counters between the initialization and the next call to advance the system.
The interface to Ginkgo batched linear solvers has been updated to fix build errors when using 64-bit index types. Note, only the batched dense matrix in Ginkgo is currently compatible with 64-bit indexing (as of Ginkgo 1.10).
The SPRKStep module now accounts for zero coefficients in the SPRK tables, eliminating extraneous function evaluations.
A bug preventing a user supplied :c:func:`SUNStepper_ResetCheckpointIndex` function from being called was fixed.
The Kokkos N_Vector now properly handles unmanaged views. Previously, if a
Kokkos N_Vector was created from an unmanaged view, the view would become a
managed view and the data would be freed unexpectedly.
A bug was fixed in KINSOL where the information logging function would always be called even when informational logging was disabled.
Deprecation Notices
SUNDIALSFileOpen and SUNDIALSFileClose will be removed in the next major release.
Use :c:func:`SUNFileOpen` and :c:func:`SUNFileClose` instead.
The Convert methods on the sundials::kokkos:Vector, sundials::kokkos::DenseMatrix,
sundials::ginkgo::Matrix, sundials::ginkgo::BatchMatrix, sundials::kokkos::DenseLinearSolver,
sundials::ginkgo::LinearSolver, and sundials::ginkgo::BatchLinearSolver classes have
been deprecated and will be removed in the next major release. The method get, should
be used instead.
The CSC_MAT and CSR_MAT macros defined in sunmatrix_sparse.h will be removed in
the next major release. Use SUN_CSC_MAT and SUN_CSR_MAT instead.
The N_Vector_S typedef to N_Vector* is deprecated and will be removed in the next major release.
The CVodeSetMonitorFn and CVodeSetMonitorFrequency functions have been deprecated and will be
removed in the next major release.
