Re: Import of tcl

Dear user, We do not support importing an existing TCL file. And we are not going to implement it at the moment because it will take too much effort, and even if we do it, what you would import is an already-discretized mesh, while STKO works with CAD Geometries (curves, surfaces, solids). The main ...

Re: Problem with Fiber sections in analysis

Moreover I noticed that you are running opensees manually from the command line. It is fine, but it will be easier for you if you run it from STKO.

You can add new opensees version in the analysis step Kits. If you don't know how to do this, please repy to this post and I will explain.

Re: Problem with Fiber sections in analysis

Dear User, the -GJ Option is not something that you should pass to the command line.
It is the optional linear torsional behavior of the cross section(G (shear modulus) * J (torsional constant)).

Please, edit the fiber cross section and do this:

Re: Problem with Fiber sections in analysis

Dear User, We couldn't replicate your issue because we were using our own version of OpenSEES. Instead you are using the latest compiled version from the official website which is 3.1.0. So we downloaded it and in fact we could reproduce your problem. Looking into the source code we noticed that the...

Re: Free Field & Lysmer Kuhlemeyer Boundary Condition

We are glad you solved your problem. Yes if you do it as a transient, you have to make sure the time step is large enough to make it quasi static. However self weight in OpenSees is always applied all at once (i.e. without timeSeries) so the gravity analysis is always a problem if you do it transien...

Re: Remove soil layer

Dear than, As I said, at the moment you can do it via the CustomCommand (TCL Script). Attached you can find a (zipped) SCD file where I use the TCL custom command to remove elements and nodes as a function of space and time. However there are some subtle issues with this approach (that's why we are ...

Re: Error in running analysis of simple beam-column assembly

Of course, send it. However I am pretty sure you are typing your coordinates correctly, but maybe you are using a wrong workplane. Note that workplanes in STKO work like in AutoCAD: If you have a workplane in the XZ plane (for example if you moved ot the front view) and then you type "10.0 10.0 0.0"...

Re: Problem with Fiber sections in analysis

Dear User, I could run your model without any problem. The file seems correct and well built. I think the problem is elsewhere. Are you using the OpenSEES version distributed with STKO? Or are you using your own version? Can you try to run OpenSees.exe manually? go in the directory where you have yo...

Re: Problem with Fiber sections in analysis

It is a crash in OpenSEES. Unfortunately there is no error message. Can you please post your *.SCD here so that we can have a look?

Re: Material Test

Dear thanh,

If you downloaded STKO+OpenSEEs, then OpenSees.exe should be located here: "C:\Program Files\STKO\opensees\bin\OpenSees_303\OpenSees.exe".

If you downloaded only STKO, that you don't have our version of STKO. Please check the existance of the abovementioned executable.

Let us know
