[Scilab-users] xcos_simulate()

[Johan Lafitte]

Hi,



My xcos model becomes quite large and takes time to compile. In order to
launch batches and optimisation process, it seems possible to compile the
model juste one time.

However, I meet the same difficulties as described in this post :

Indeed, the following script...


*  ___________________________________ *

*loadXcosLibs;*

*importXcosDiagram("C:\Users\johan\OneDrive\Micro
entreprise\Technique\Kayak guide\Modélisation\Scilab\optimisation"+"\modèle
physique et commande simple_10_opti.zcos");*

*tic();*

*xcos_simulate(scs_m, 4);*

*disp("méthode 2",toc());*



*tic();*

*%cpr = xcos_compile(scs_m);*

*disp( "Durée compilation",toc());*



*tic();*

*xcos_simulate(scs_m,1)*

*disp( "méthode 1",toc());*

...gives the following results :

 ___________________________________

*"scicos_simulate step 1"*

*   50.813412 s*



*  "scicos_simulate step 2"*

*   57.440604 s*



*  "xcos_simulate(scs_m, 4) méthode 2"*

*   58.808546 s*



*  "Compilation duration"*

*   55.615238 s*



*  "xcos_simulate(scs_m,1) méthode 1"*

   *61.133700 s*

It seems the compilation step is done in all these cases.



*Thank you for your time and for your help*

note 1 : when the final time of the simulation is set from 20s to 200s, the
execution time increases about 15s



note 2 : according to the windows task manager, CPUs seem to be used about
30% during compilation and about 100% during simulation which takes few
seconds
