Linear Elastic Pushover help needed! please :) :)

[Edwardsimm]

Hi, I hope someone can help.

I trying to perform a linear elastic pushover simulation but when i run the code in OpenSees.exe it does not create the Disp.out file or the Force.out file?

I hope someone can help as i really need this simulation to work for my Dissertation.

Hi
I checked your code and ran it in opensees.exe, it's completely correct and Opensees created disp.out and force.out for me.
Try another ver. of Opensees and make sure required activeTCL is installed!!!!(I used 2.5.0 ver.)

[Edwardsimm]

Hi, Thank-you for the quick response!

I have re-installed active TCL and checked with using puts $tcl_version and the version is up to date -8.5. I have also checked my OpenSees terminal and it is up to date using 2.5 version

When I run the file - pushover, using the source command, the only feedback I receive is the following- a single 0 ?

OpenSees > source /Users/edward/Desktop/untitled\ folder/Example/Pushover.tcl
0

I am not sure where to go from this considering the code is correct.

Hi
I checked it again and couldn’t see any problem.
Here is your code and output files:
https://www.dropbox.com/s/9njjrpo869k6w ... d.rar?dl=0
I recommend you to copy opensees.exe to your code path then run it.(OpenSees-> source Pushover.tcl)

[Edwardsimm]

Thank-you so much for running the code and placing it in a drop-box file.

I will have to get it sorted, i have trying to install the OpenSEES.exe with the folder, but still comes up with the same problem.

I am running it on a mac, but surely, that shouldn't make a difference?

Also did you path the file after you installed it, because I have done that? and not sure if I need to?

[Edwardsimm]

Hi Emrani,

Just quick Q, do you have any of the extensions installed? or just OpenSEES.exe?

Thanks a-lot
