Hi,

I am modelling a monopile using a combination of beam and continuum elements, embedded in sand, which I have modelled using SanisandMS. The top of the pile is subjected to a monotonic push, and I would like to extract the force required to move the pile as well as its displacement at ground ...

Hi,

I tried the simple Newton approach, but non-convergence seems to happen earlier than when I use the KrylovNewton algorithm.

The error i received is:

WARNING: CTestNormDispIncr::test() - failed to converge
after: 1000 iterations current Norm: nan (max: 0.001, Norm deltaR: nan)

Hi,

By simple Newton, you mean the most basic one? Without modification or line search.

algorithm Newton <-initial> <-initialThenCurrent>

Would there be any suggested input for <-initial> <-initialThenCurrent> that can help with this convergence issue?

Sincerely,
Ryan

Hi,

I am attempting to analyze a monopile embedded in sand, which is modeled using the SanisandMS material model. The pile is subjected to a load of approximately 2.5 meters at the pile head. The analysis successfully runs until a movement of 1.45 meters is achieved at the pile head. However ...

Hi,

While running my analysis. i received this error :

HDF5-DIAG: Error detected in HDF5 (1.14.0) thread 0:

I am currently using STKO for post-processing.

I have another question: I am also utilizing OpenSees' built-in recorder system. One reason I use the "remove recorder" command is that I want to separate my text results between different stages of analysis into separate text files. Is there a way to ...

"Alright, this seems helpful. I will give it a try. Thank you!"

Hi,

Thank you for your reply. I understand what you mean.

Is there a way to view the Gauss point plot for the model analysis that I'm attempting?

Hi,

In my analysis, I am using two material models: one for stage 1 of the analysis and another material is added for the subsequent analysis stages (2 materials now in stage 2). When I save the results in a single MPCO recorder that incorporates both model stages, I can only view the stress-strain ...

Hi,

I'm using STKO for post-processing. Here is the code I used for the MPCO recorders in my TCL script:
You can ignore " x " as it is a file location.
