[Scilab-users] Phase shift and step size - electrical (XCOS)

[Michael J McCann]

I mostly use Matlab and Simulink or my own software but I can see that 
in Xcos I can define parameters that control parameters  inside the 
blocks.   The Simulation menu item in Xcos has the option to define the 
integration method and there are some choices you can make about maximum 
stepsize for Runge Kutta, which is basically a fixed step approach but 
they may be embedding it in a variable step size environment so it will 
make adjustments (to smaller steps). There is within the [Simulation] 
item a [Set Context] option that allows you to deliver numeric values 
into the simulation as well. Also, I suspect that if you specify a clock 
to drive the sampling of a "scope" you can implicitly define a maximum 
step size.
With regard to the operations of multiply and divide I'd say "be 
careful" because a division is a strange thing to have in a real 
physical system so I'd be looking at your understanding of the system 
you were modelling and ask why it appears at all.
Hope this helps
