Where are the system variables?

[zhan]

Hello everyone,

Where are the system variables stored when we are using Opensees?
System variables are variables like:
Material tag;
strain(n);
strain(n+1);
...
etc.

Thank you so much.

its an object oriented program .. each object stores whatever data they need .. strains for example are stored in each instance of a mateial object that has been created.

Thank you FMK,

Thank you for pointing it out to me.
I got my code working now.

Now when I define my parameters for my own object,
how do I output my defined parameter?

For example:
I have a variable fp (it's a vector length 2) defined for the object.
Then in my file MyObject.cpp, I have everything declared and the following:

const Vector&
MyObject::getfpvector(void)
{
x...........x // all the code to calculate vector fp

return fp;
}

My object in each loop gives a 1x2 vector;
After all the analysis, I expect to have a matrix of fp nx2.

Then, what I need to do if I want to out fp to a file in TCLeditor?
what do I need to record?

Hope my question make sense.
Thank you!

I will bring up another this issue as a new topic.
