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)).

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.

QzSimple1 suction

Hi guys I am modelling an open foundation on a bed of q-z springs. I tried with both QzSimple1 and QzSimple2 materials with suction 0.0. When I run cyclic push-pull analyses just to check the material response, I always get some suction values. Is it a default parameter of 0.1qult irrespective of us...

chord rotation of a column

Hi Guys I modeled a bridge abutment column by 10 displacement based elements with 5 integration points in each element. This discretization is necessary to incorporate lateral resistance from backfill soil. As a part of assessment, I need to know the chord rotation demand of the overall column eleme...

Input of 6x6 matrix for foundation stiffness.

Hi guys

I am wondering whether it is possible to give a 6x6 coupled stiffness matrix as a replacement of pile group. I can use zero length element, but that will give just the diagonal terms; without any coupling among them. Any idea....
