Veselin Dobrev 9310e05a15 Override appropriately the SetPrintLevel methods in class KINSolver 2021-12-20 16:20:27 -08:00
Adrien M. Bernede f4dbd3743d Applying Astyle 3.1 2021-09-03 12:14:24 -07:00
Aaron Fisher e758c37691 Removed nearly all leading underscores for variable names. Every once in a while one of these will confilct with standard libraries in an oddball compiler and it's best to just avoid this problem alltogether. 2021-05-10 16:06:51 -07:00

Veselin Dobrev ca7cf33e51 In class CVODESSolver, add a wrapper for CVodeSetMaxNumStepsB 
and use it in miniapps/adjoint/cvsRoberts_ASAi_dns.cpp to
increase the default value.

Balos, Cody Joe c36d6ca2b1 sundials-gpu-dev: a couple minor fixes 2020-09-21 08:57:45 -07:00
Balos, Cody Joe a5bb313e52 Update to SUNDIALS 5.4.0 RC 
This has no changes to the CPU only code (all changes were in
MFEM_USE_CUDA ifdef). The primary change is that mfem controls the
lifetime of the SUNMemoryHelper, thus the SundialsMemHelper class and
mfem::sunmemHelper were added.

Balos, Cody Joe 6f78235cfe keep sundials backwards compatibility when not using cuda 2020-08-26 13:20:36 -07:00
Balos, Cody Joe 937db1a293 Add support for SUNDIALS GPU features 
Add support for SUNDIALS CUDA features. These changes will be easily
extendable to support future GPU features in SUNDIALS, e.g. HIP
features. To keep things clean, this creates a SundialsNVector
class to interface with the SUNDIALS N_Vector. This class inherits
from the mfem::Vector class, and follows the pattern used in MFEM
interfaces to other libraries such as PETSc and hypre.

Jonathan Wong c933973249 Initial CVODESSolver implementation. Simple serial and parallel problem solved. Added Rootfunction finding and error control support 2020-01-06 15:40:05 -08:00
Veselin Dobrev 22e4c1ccbf Fix the serial build with SUNDIALS. 2019-11-05 18:04:05 -08:00
Veselin Dobrev 7a869c30c6 In class TimeDependentOperator, add a new property: evaluation 
mode, see TimeDependentOperator::SetEvalMode() for description.
This new property is now used to support IMEX time integration
in class ARKStepSolver. With this addition the method
TimeDependentOperator::SUNImplicitMult() is no longer needed
and was removed.
 2019-10-11 23:37:49 -07:00
Veselin Dobrev 959eea2830 Some small tweaks: 
- Apply 'make style'
- Add a note in the CVODE/ARKODE/KINSOL Init() methods that
  re-initializing may purge some user-set options
- When updating the operator of the CVODE/AKODE/KINSOL objects in
  their respective SetOperator() methods, use an all-reduce to
  make sure all ranks do this in a consistent manner.
