DASPK Integrator #20

Closed GoogleCodeExporter closed 6 years ago

GoogleCodeExporter commented 9 years ago
DASPK integrator can't be used for some reasons:

1. Function names in Fortran code not unique. For this reason the whole 
integrator isn't compiled (see Makefile.am)

2. The integrator is implemented as an ode integrator. It may be implemented as 
a dae-integrator (see kernel version 0.1.3)

3. The integrator doesn't call system->update() during the integration. Only 
system->plot(), but not in every timestep.

Suggestion:
- The DASP integrator should be removed in this version
- A DAE integrator should be implemented. Maybe a Radau5DAE? In kernel version 
0.2.1 two DAE-Integrators where implemented (DASPK, Radau5DAE) from Robert 
Huber.
