Re: [Scilab-users] Reading an xcos diagram with scs_m

[Clément David]

Hello,

Do you use any hierarchy ? If the current `scs_m` level is exported it might be 
sufficient in my
view.

Can you open a bug describing your need ? I will try to implement that for 
Scilab 6.0.

Regards,

Re: [Scilab-users] Reading an xcos diagram with scs_m

[Nazreen]

Dear Sir,
In my Xcos diagram file, I am not using any simulation
functions. Basically I just want to retrieve stored data from all the blocks
(using the scs_m and scs_m.objs). The "Solver" is setup on a block. I coded
the block in such a way that when one clicks on the block, it executes a
file (which runs some instructions and functions). So i would like the
block, on clicking it, to be able to tell which file is in use (if many
files are opened in xcos) so it can retrieve the data from that specified
xcos file and then carry out the calculations.
 
My files are shown above. As you can see, the same Solver block ("Solve
Power Flow") is in both files. I would like the function of the block to
importXcosDiagraam("desired xcos file"). So i would like to retrieve the
scs_m of one file when many are opened.
Regards,
Nazreen.

Re: [Scilab-users] Reading an xcos diagram with scs_m

[Clément David]

Hello,

On Scilab 5 there is no way to retrieve the current diagram while opening a 
block. To cover your
needs I suggest you to take a look at the simulation hook. This is some 
functions called before and
after the simulation.

In Scilab 6, it is possible to get the parent diagram but we currently provide 
no documented way to
achieve that. Can you clarify your needs ? Do you setup the solver on a block ? 
What kind of
information do you need ?

Re: [Scilab-users] Help with bvodeS & bvode and unusual boundary conditions

[Serge Steer]

in zeta you will give the locations (relative to y) of your boundary
conditions
in your case something like [0 0 0 , L  L L ]
if you have 6 states 3 with initial constraints and 3 with final contraints
The constraints  should then be defined by the gsub  and dgsub functions

[Scilab-users] Help with bvodeS & bvode and unusual boundary conditions

[amonmayr]

Hi everyone,

I'm trying to understand how bvodeS works and whether I can use it to 
solve numerically my problem.

A bit of context:
I have a 1D coupled-mode problem, where I model the propagation along 
one direction (let's call it y) of two modes (one in +y-direction and 
one in the -y-direction).

Schematically, it looks like this:

a(0) -->| ODE |-->a(L)
b(0) <--| ODE |<--b(L)

The ODE is of the first order (only a(y), b(y) and a'(y) and b'(y) in 
the ODE, together with non-constant factors).


The thing is that I have scattering-like boundary conditions.
I know the inputs [a(0)=a0;b(L)=bL] and look for the outputs [a(L)=?; 
b(0)=?].
I am of course also interested in  the values of [a(y), b(y)] for all y 
in [0,L], but the puzzling issue are my boundary conditions.
I basically half of my conditions on one side, the other half on the 
other side.

Can I solve such a system using bvodeS?
If I can, how am I supposed to build "zeta" to reflect that my 
conditions only concerns a(0) and b(L)?

Is this doable to get zeta "with holes"?

Thank you in advance for your help,

Antoine
