I have a model with 3 parameter blocks containing a lot of constants. I would like to know how can i print those lists to papper, .pdf, word or something like that.

Thanks

hi,

I am trying to make a custom on maple but when i get an error on dynamicSystems saying:

> sys := DynamicSystems[AlgEquation](eq, inputvariable = [Altura(t)], outputvariable = [Teste(t)]);
Error, (in DynamicSystems:-AlgEquation) algebraic equations cannot depend on past/future values of the input/output

But if i change AlgEquation to diffEquation i get no error. I dont have any diff equation on the system. This is happening with one of the "equations":

Hi,

i am trying to simulate a costum component, but i get this error when starting to compile initial values i get this error:

(in dsolve/numeric/RunSimulation) keyword event_blindeye not recognized
Simulation failed.

Why? This costum component was tested on another PC and worked.

 

Thanks

I would like to know if it is possible to declare some variables in one parameter box (i would call it independ parameters) and other with parameters that depends on the first ones:

L=5

m=2

k=arctan(m/L)

 

(for exemple)

 

THanks

Hello. I am creating a custom component similar to the one that maplesoft has as an example (the discretized counterflow heat exchanger), but with some diff. The problem is that when i execute dyamic systems i get an error saying:

Error, (in DynamicSystems:-ParseSystemInputs) cannot match the arguments to an appropriate system

Is this a problem on my equation (something that i may have forget) or is another thing? Are the arguments type of dynamic system in the right "type"?
