vfo error #15

error message graphical interface

I am getting the following error while plotting the deformed shape for my Pushover analysis. I get ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Also, the slider shows a negative time step. Is it normal to have a negative time step value?

However, I can view the model. What could be the problem here?

Thank you.

For a pushover analysis, the slider shows the analysis load factor. For a time-history analysis, it will show the time step.

I am not sure what the problem is. Could you share the ODB folder so I can take a look? Upload on your GitHub account and share the link.

https://github.com/rameshadhikari07/vfoPushover/tree/main/1MRF_ODB I realized that one of my element tags had 7 digits. I changed that, and I could see the deformed model. However, the amount of deformation does not change even when I drag the slider. Furthermore, the slider shows the load factor, is it normal to get a negative load factor?

Now, I am getting a new issue while plotting the mode shapes. I get the following error: image (I created an ODB as vfo.createODB(model='1MRF', Nmodes=10, loadcase='Pushover'))

However, I successfully ran an Eigenvalue analysis in Opensees using the eigen() function.

The error shows the eigen analysis failed.

The negative load factor in pushover analysis is common and depends on the model.
