I have a problem with the variables to simulate because I do not collect the good of the model, gave me a weird number
-1.2980.... and presumably that means that it has not begun the simulation, but if you started.
Because I have:

result=vensim.command("SPECIAL>LOADMODEL|C:\\Documents and Settings\\miriiam\\Escritorio\\PROYECTO\\mariaje\\MODELO\\ACI118MO00\\CIMD9.vmf" );
result = vensim.command("SIMULATE>RUNNAME|base.vdf");

Someone can help me please?

Use vensim_get_data to retrieve values from a completed simulation. vensim_get_val will not work.

With that work for me either.
I put: vensim.get_data result = ( "base.vdf", "initial price [producto1, competidor1]," "Time", rval, precioinicial1, 36), but not if it is correct as well.
What we had was:
Cargo model, collect the variable value to put in a box with vensim.get_val result = ( "initial price [producto1, competidor1]," precioinicial1);
but the variables are not reflected well, the only constant.
I tried to put before collecting the variable:
vensim.command result = (TEST> Shopping store [producto1, competidor1]> 0 ");
and work for me but only for some.
I do not understand.
Sorry for the English!
Please HELP

The get_data call should work - as you have entered it there are errors in the " placement so be sure that does not happen i n your code. Also both rval and tval (precioinicial1) need to be vectors with at least 36 spaces. eg use


private int tpoints ;
float rval[], tval[];

// create arrays for time and values, hardwired array length
tval = new float[41];
rval = new float[41];


tpoints = vensim.get_data( "base.vdf", "Population", "time", rval, tval, 41 );

as in the exmaple VensimApp.java

Thank you so much! already got it but now what I fault is that when I pretend to, do this:
vensimCommand = "simulates> SETVAL | initial price [producto1, competidor1] =" + PrecioInit1;
vensim.command result = ( "MENU> RUN | 0");
And then to pick the outcome of the simulation:
tpoints = vensim.get_data ( "base.vdf", "EBITDA", "time", rval, tval, 41);

but I get the bug to do:
vensimCommand = "simulates> SETVAL | initial price [producto1, competidor1] =" + PrecioInit1;
for variables alone, because for the continuing work for me either.

I could help? Thank you so much

I have already achieved what we got before, thank you very much alike.
Now to collect the return value of the simulation to be put?
this:
vensim.get_data result = ( "base.vdf", "EBITDA", "TIME", EBITDA, tval, 41);
is that I did not get to work

Thank you very much;)

You will need to show actual code including variable declarations for me to make any sense of this.

Thank you very muchTextMY PROBLEM STARTS FROM HERE:(:(:(:(:(:(

The three thing I can see wrong are:

EITBA has only 36 elements but you are telling Vensim it has 41. If the simulation has more than 36 saved points behavior will be unpredictable. )You also need to double check that EITBA is a model variable. )

The SIMULATE>DATA commands should be SIMULATE>SETVAL commands.

MENU>RUN|0 should be MENU>RUN|O (oh instead of zero).

I have reviewed what I've said and still does not work.
The error gives me at:

tpoints = vensim.get_data ( "base", "EBITDA [company]", "TIME", EBITDA, tval, 36);

Because It returns me a 0 and that means it does not find the variable not?

And if this variable there!

Thank you

This will not work if company is a subscript range. Rather you will need to call it with subscript elements as in:

tpoints = vensim.get_data ( "base", "EBITDA [competidor1]", "TIME", EBITDA, tval, 36);

clearly once for each company you want values for.

I have already achieved
Now I have a doubt, when we put:

tpoints = vensim.get_data ( "base", "EBITDA [competidor1]", "TIME", EBITDA, tval, 36);

The base.vdf must exist? or you can put a. VDF and white that simulates what there?

I am not sure.

I would appreciate if someone explain the function. VDF there

Thank you very much

Before you simulate you have the command SIMULATE>RUNNAME|base - thus when simulation occurs the file base.vdf file be created. The get_data call must refer to an existing run. Whether you pass "base" or "base.vdf" as an argument does not matter - Vensim knows all runs have extension .vdf.

Thank you very much for everything.
Now I have the following problem: I have my application and any value of the variables to get the same result of the simulation.
If you run the program vensim leave the correct data to the model.

Someone can help me?

Thank you very much

You need to load CIN files, add data files or change an Excel source.

What data does your model need to run?

My model need variables to run.

What´s the CIN files? We don´t understand what you mean.

Where do you store the variables? Do you use CIN files, data files or Excel?

we store variables in .vdf

We do:

*Load the model
result = vensim.command( "SPECIAL>LOADMODEL|C:\\Documents and Settings\\miriiam\\Escritorio\\PROYECTO\\mariaje\\MODELO\\ACI118MO00\\CIMD9.vmf" );

*Get the initial values
result=vensim.get_data("base","precios[producto1,competidor1]","TIME",precioinicial1,tval,36);

*Simulate
result = vensim.command( "SIMULATE>RUNNAME|base" );

*Catch the result
tpoints = vensim.get_data( "base", "EBITDA[competidor1]", "TIME", EBITDA, tval, 36 );

[Edited on 9-25-2008 by vero]

How do you run the model in Vensim?

In your example, you are reading results from a run, and then overwriting that run. You are not reading any source data at all.

We run the model with:

result = vensim.command( "SIMULATE>RUNNAME|base" );

And how we can read any source data???

The base already exists and we want to run in this vdf, overwriting and read the new results.

Please help us

I can't understand the question.

If you are seeing different results running a model in Vensim and through the DLL then simulation using the DLL to one name, and in Vensim to another. In Vensim you can then load both models and use the Runs Compare tool to see the differences.

I have the problem here:

Someone could help me?? thank you

If SETVAL is working for other constants, then you must either have a spelling mistake, or the calls to SETVAL producting the errors are trying to set constants that are not in the model.

Can you post the model?

Tony.

SETVAL not work for me because I got there just in another place like

PrecioInit1 = cprecio1.getText();

vensimCommand = "SIMULATE>SETVAL|precios [producto1,competidor1] = " + PrecioInit1;

result = vensim.command( vensimCommand );

and if that work for me.

The variables exist in the model


I want to do is pick up the initial values of these variables and put them in the fields inputs


Thank you

If you want to get values, you need to call vensim_get_val.

For example,

float rval;
result = vensim.vensim_get_val("precios[producto1,competidor1]",rval);

if (result == 0)
System.out.println( "vensim_get_val - failed" );


You need to make sure you pass rval in correctly to the function call.

Tony.
