Thnaks for the precisions Joe

I will take some more time to study the Modelica outputs then, but for me most of my simulations are a mixture of algebraic equations and block build items (the later typically for a mechanical geometry/structure). But everything can not easily be put into blocks, I need the equation inputs. I.e I have a non-linear spring (linking two parts of my structure) that depends on the local position of my structure. This implies acting on the spring constant k(x), I do not see how to get around only by adding forces ;)

Well more work for me, it will not be as easy as hoped, but lets see the nice side, I'll learn something new ;)

Thanks again

Hi Joe

Well then I'm missing some of the interest in MapleSim, I need to be able to loop my variables such that i.e I have a spring constant "k" that changes with position, or that I adapt a value as function of time.

for me the variables x,y,z and t should be adressable in my variables. For x,y,z I need to ba able to use my own references too, I can set a relative position sensor, but then I ne to feed it back into a variable of another block

Thanks,

this work-around looks great, it will save me hours of clicking

I hope Maple will add soon a global plot time axis selection in their plot window, as often one want to skip the first 1-2 periods to leave your system settle (and to avoid the spikes that scales your graphs out of usefull range)

So long

And if I have a piecewise function (continuous derivable to the "jerck"), depending on a several line internal function, how can I get that into a block such to replace the simpel "real-signal Sine" block ?

Because none of the templates are right fo that, I have a function not a series of data points, nor a PDE

Thanks in advance
