[Scilab-users] Sundials module, Windows preview

[CHEZE David 227480]

Dear Stephane, I did give a try to windows build, limited to my use case, and it works like a charm !
I just ran a previous use case with cvode() (solar thermal panel quasi-dynamic model, comparison with experimental data set ), as it was written for the external Sundials module you developed previously (~January 2022) : same performance in execution time as expected since relying on the same code isn’t it ?

I appreciated the improved documentation details and I just started reading documentation of the new features from the windows Sundials Scilab builtin : arkode, ida, kinsol : it looks exciting for future use cases.

Thanks again for introducing these key features, is there any news about the next Scilab release ?

David

Hello,

Did anybody give a try to the Windows build ?

Frankly speaking, if nobody cares about improved numerical methods in Scilab, things can be left as is, and time could be spent on other features (but not by me...).

I can also prepare a Linux build, if users of this os want to test...

Regards,

S.

Hi all,

The next version of scilab will include a new module "Sundials". This module provides new full featured  ODE solvers: arkode(), cvode() and DAE solver ida(), all handling complex numbers and dense/sparse/banded Jacobians. Each solver has specific features, e.g. ida() handles DAE, arkode() handles mixed implicit/explicit Runge-Kutta methods and cvode() can do forward sensitivity computation.

The module also includes a general-purpose nonlinear system solver: kinsol(), who takes advantage of the module architecture (parsing, computation engine and SUNDIALS abstraction of various linear solvers).

Current help pages can be found @ https://www.utc.fr/~mottelet/scilab/sundials/<https://antispam.utc.fr/proxy/v3?i=SHV0Y1JZQjNyckJFa3dUQiblhF5YcUqtiWCaK_ri0kk&r=T0hnMlUyVEgwNmlmdHc1NTiGTQVgIg9a1MYkHb_GeosOO-jCQ_NnAucfYCLceioT&f=V3p0eFlQOUZ4czh2enpJS67gBdM2WVME2HqVPefA4FpGU6HeKhrEzrhzAHs-d_Wu&u=https%3A//www.utc.fr/~mottelet/scilab/sundials/&k=ZVd0> and a Windows build of Scilab (in addition to the already available macOS build) including the new module is available at

The help pages propose a lot of examples and two demos (this section is to be enriched) are available.

Comments are welcome !
