OpenSees-MATLAB

Hi,

I would really appreciate if someone could tell me how to analyze a model built in OpenSees (a tcl file), via MATLAB. In other words I want to have a link between OpenSees and MATLAB. First I should run OpenSees and then write 'source inputfile.tcl' in the command prompt (which is OpenSees here) through MATLAB. I want MATLAB`s associated commands.

Thanks

ask the guys who wrote OpenSees Navigator.
But are you sure you want to carry the Matlab burden during analysis? it'd really slow things down...

Thank you for your reply
I`m going to build some models automatically with MATLAB, analyze them with OpenSees, compare the results and find the best one. So I think I have to use MATLAB.
Another choice is to run m files with tcl commands. Do you have any information in this field?

you can use Gid as pre-processor as well as post processor with some coding,
and run opensees from Gid itself

why not in tcl?

I think I will face difficulties in post processing analysis with tcl, while MATLAB is more powerful in numerical and graphical calculations. That is why I need running m files with tcl commands or tcl files with m ones.

simply go to the directory where opensees and inputfile.tcl reside and then run opensees as a system command from Matlab:

For example, within Matlab, if your files are in c:\opensees,

>> cd c:\opensees
>> opensees inputfile.tcl

I hope this helps.

oops, correction:

>> ! opensees inputfile.tcl

Does anyone know how to input a vector in Matlab as ground motion in OpenSees?

I want to do this without saving vector to file and using file as ground motion in Tcl.

Will I be able to do that?
