What you are trying to do is unclear. Can you give more explanation?

Thanks Prof. Scott, the issue has been solved. I meshed the beam and constrained its lateral movement with the fix command.

Hello there,
I want to constrain the lateral movement of a simple elastic beam in 3D space. Since the Fix command only works on nodes, how can I implement this?

Dear Professor Scott, It turns out that OpenSees had calculated the frequencies correctly all along! Upon further investigation, I discovered that I had meshed my model in Abaqus using B21 and B22 elements (2-node linear beam and 3-node quadratic beam), which resulted in similar results when using t...

The list of frequencies (Hz) provided by abaqus is 292.59, 516.88, 545.88, 776.87, etc. whereas the results provided by opensees is 516.87, 736.68, 1031.72, 1542.49, etc.!

Hi, I performed an eigen analysis on a 2D elastic beam with fixed BCs. But the results differ significantly from those of abaqus. Is there anything wrong with the following code? Best regards, import openseespy.opensees as ops import numpy as np ops.wipe() # Create model ops.model('basic', '-ndm', 2...

Hey guys,

In 3D Elastic Beam Column Element, the releasez and releasey, release Mz and My at the nodes in local coordinates?

element('elasticBeamColumn', eleTag, *eleNodes, secTag, transfTag, <'-mass', mass>, <'-cMass'> <'-releasez', releaseCode>, <'-releasey', releaseCode>)
