Re: MPCO RECORDER ERROR

This is because probably you are trying to extract both displacement and reaction at the same node (control node).
However, it does not have any reaction.

Instead in the monitor, I use the control node for displacement and the base nodes for reactions

Re: MPCO RECORDER ERROR

Adding to what Clarabella said to deselect you need to press ctrl and select the nodes you like to deselect. , you can press ESC to completely clear your previous selection. This is the standard behavior in most CAD modeling applications. The selection remains until you clear it by pressing ESC. If ...

Re: More than one zero length material at a single node

Interactions cannot be copied, due to the concept of master-slave pairs... Creating a lot of zero-length interaction is always tedious. If you know Python you can create your own custom python component (a new Physical property and a new Element Property) as we did for the MasonryInfillWallMaterial/...

Re: Excavation problem

Dear Yu-Wei, We are currently implementing it as a built-in command in STKO. In the meantime you can use a custom script as shown in this example file: excav.zip To do this, you need to use this new updated "region" command, place it in "C:\Program Files\STKO\external_solvers\opensees\analysis_steps...

Re: MPCO RECORDER ERROR

Here is the working file: Frame.zip The problem was the elasticForceBeamColumn element. It has a problem with the output. In any case, I don't think you wanted to use the elasticForceBeamColumn , because it is elastic... So I changed it to forceBeamColumn and it works now. In the attached file, I ma...

Re: Importing from tcl

That location only existed in previous version of STKO that included OpenSees. Now OpenSees is not included anymore with STKO, that's why you don't find that folder.

Anyway, if you need the HDF5 dlls, they are in the C:\Program Files\STKO (hdf5.dll, szip.dll, zlib.dll)

Re: Analysis Problems

Yeah you are right, We fixed it in version 2.0.0 that will be released soon (not in version 1.1.5) In the meanwhile, here's the fixed "monitor.py" file: monitor.zip You can un-zip it and copy it in "C:\Program Files\STKO\external_solvers\opensees\analysis_steps\Misc_commands " replacing the existing...

Re: More than one zero length material at a single node

Do you mean that you want to create 2 zero-length elements sharing the same nodes?
In this case, just create 2 interactions (overlapping) connecting the same master-slave pair.

Re: Nodes without element property

The error says that the lambda in sqrt(lambda) is not in the valid range for the sqrt funciton. It means that you have a negative eigenvalue. It can happen when your model is not well constrained, or when you run an eigen command after your structure goes into a softening stage. Make sure your model...
