Re: MUMPS solver
If your model is not large (2D soil column), you won't see much time difference with any of the solvers.

Re: fiber section stress-strain output through recorder command
A better workaround is to cast the numeric values as strings in Python. It is only a problem for numeric values that come after 'section', 'material',or 'fiber'. Not a problem with node recorders as you pointed out.
ops.recorder('Element','-ele',1,'section',str(5),...)
ops.recorder('Element','-ele',1,'section',str(5),...)

Re: How to Get Section Geometry
There isn't a recorder option for the fiber locations and areas, but there could be. Can you create an "issue" at the OpenSees GitHub page?

Re: Problems in modelling 'Fiber Thermal' section for 3D analysis
I found the issue and checked it into GitHub:
https://github.com/OpenSees/OpenSees/pull/371
Should be in the next pip upgrade, but I will also need to fix some of the -GJ code, so stay tuned.

Re: Problems in modelling 'Fiber Thermal' section for 3D analysis
Thanks for sharing your code. I also get a segmentation fault for the fiber command in the 3D model. It's probably an input parsing error. I will check it out.

Re: How to Get Section Geometry
There's not an easy way to get the section geometry from a fiber section. You can get the fiber locations and areas and make your best guess from there.

Re: fiber section stress-strain output through recorder command
I think the recorders have less overhead than the output commands, but I haven't quantified it.

Re: Is there a program that converts Tcl into PY files?
This script works, but only if the Tcl file defines everything line by line, i.e., without loops, conditional statements, or variable substitutions.

Re: Load cases and Load Combinations
You end up with two loads applied and after two time steps with linear time series, you get four times the displacement. You will need to use 'Constant' time series for gravity loads. Or 'Linear' time series but you have to reset the time to zero before you apply time varying loads.

Re: Opensees Saws material code
Do you have the same issue with the Tcl version of OpenSees? I ask because it could be a problem with the inputs or with the material implementation, e.g., revertToStart. Generally, we need more information than what you provided.

Re: Software error in update material function (updateMaterialStage)
Can you provide a more complete minimum working example? The code you posted does not define any materials.

Re: Problem in sharing .py file as it is indent based program
Good point. I enabled BBcode, so now you should be able to use delimiters around your Python code
app.php/help/bbcode#f2r1
For example:
app.php/help/bbcode#f2r1
For example:
Code: Select all
for i in range(5):
print(i)

Re: question on stiffness damping coefficient
To get the matrices M, C, and K, read this: https://wp.me/pbejzW-FH
Also, you need to use the -file option, 'printA -file 2.txt'
