Re: eleType

Hi Michael,

Thanks for your quick response.

I'm using the "ShellMITC4" element. The eleType returns UnknownMovableObject and getEleClassTags returns 53.

The line element objects, namely dispBeamColumn3D and TrussSection elements work fine.

Thanks,
Gopal

eleType

Hello,

I'm wondering whether 'eleType' command is implemented for quad or similar elements?
I found it works with zerolength and line elements.

Thanks,
Gopal

Re: Extract fixity condition of nodes

Hello again, I am modelling a SSPquadUP element. Bottom nodes are fixed for displacement and top nodes are fixed for pore pressure only. ops.fix(1, 1, 1, 0) ops.fix(2, 1, 1, 0) ops.fix(3, 0, 0, 1) ops.fix(4, 0, 0, 1) When I requested nodeDOF for all nodes, I got this output, as expected. [-1, -1, 5]...

Re: Hyperbolic Gap and Elastic PP Gap are not working

Thanks Prof.

It is now working in parallel with a very soft elastic spring under monotonic loading. But the material models work fine under a cyclic loading though, without any need of a soft elastic spring.

cheers,

VTK recorder

Hi all, I noted that a vtk recorder is available in the source code, but there is no documentation available. I am wondering whether someone can help with the vtk recorder. I'm using PyVista for visualization purpose. If I can get a VTK formatted output,I dont have to write a script for conversion. ...

Re: Extract fixity condition of nodes

Hello,

Thanks Prof Scott. I tried with nodeDOFs(nodeTag). Below is a part of my code.

Code: Select all

ops.fix(1, 1, 1, 1, 1, 1, 1)
print(ops.nodeDOFs(1))
This outputs

Code: Select all

WARNING nodeDOFs DOF group null
opensees.OpenSeesError: See stderr output

Extract fixity condition of nodes

Hi all,

I am wondering whether I can extract information about the fixity condition of nodes from an analysis model, similar to node mass (nodeMass(nodeTag)).

https://openseespydoc.readthedocs.io/en ... eMass.html

Thanks,
Gopal

Hyperbolic Gap and Elastic PP Gap are not working

Hi there, I was trying to use Hyperbolic Gap and Elastic PP Gap material in my analysis of a bridge abutment. It appears both models are not working with OpenSeesPy. I used both materials few years ago with tcl scripts. I am wondering whether I made any mistake in defining the material models. Below...

Re: Analyze for residual stress in steel column section

Dear Professor, There are a few number of steel sections, not all 40 piles are different. I will assign the residual stress pattern only to four sections. However, I am not sure how to define this stress pattern. I understand Steel02 can be defined with initial stress value. My plan now is to define...

Analyze for residual stress in steel column section

Hi all, I am carrying out a second order analysis of a wharf with lots of steel H-piles. I was thinking of using Steel02 material with initial stress parameter to include the effect of residual stress pattern. However, the approach would be quite cumbersome since the wharf has about 40 piles. I am w...

Re: How to run different analysis simultaneously

Yes you can do that. You can ask eigenvalue analysis at the end of each pushover step.
