Re: Debugging

Dear Alok, There are some other issues I just fixed: fixed non 4-edge surfaces changed forceBeamColumn with elasticBeamColumn (since you used Elastic section) some beam element without physical property (boundary of roof.. I unassigned them, there should be no element there) shell elements had wrong...

Re: Analysis

Dear User,
this means the model runs correctly.
To see the results, you can open the database (.mpco) in the Post Processor.

Re: Drawback with concrete stress-strain diagram

Dear user,

It is perfectly normal: the Concrete01, defines the point (epsCU, fpCU) as the last point after which you have a constant plateau:

If you want to make it drop after an ultimate strain, you need to use the MinMax material in combination with the Concrete01:

Re: connect shell wall and truss rod

Hi Chiara, From the error, it looks like you don't have a convergence problem, but you are instead using something that is not compatible with the MPCO recorder. There are few things that have a bug in OpenSees and cannot be used when using a MPCO Recorder: elasticForceBeamColumn -> use a simple ela...

Re: analysis issue

From the error it looks like that you are using a quadrilateral mesh with quadratic displacement interpolation (9 nodes) while the element you are using is a 4 node element (ShellMITC4). You have 2 options: 1) If you want to use quadratic displacement interpolation, use ShellMITC9 2) if you want to ...

Re: soil structure interaction

dear User,
the fem model is fine.
You can try to check the input parameter (material, section properties and analysis) and also to reduce time step size.
Have a nice day.

Re: Example for Lysmer+free field boundary model

Hi Yu-Wei, That example is quite old, I don't have that exact SCD file anymore. However we recently gave a webinar about SSI with absorbing boundaries which is exactly the same, but more generic (it is a 3D example) On our website you can visit the e-learning wepage were we keep track of all previou...
