TypeError: The keyword fps is no longer supported. Use duration(in ms) instead, e.g. fps=50 == duration=20 (1000 * 1/50).

Solution is to replace time.clock() according to the following link:

https://stackoverflow.com/questions/58569361/attributeerror-module-time-has-no-attribute-clock-in-python-3-8

Also, it would be nice if you could get the stiffness matrix as a function of the areas of the elements for optimization purposes!

Some recent code change stopped the important getting started example from working.

this leads to errors if the actual list of results is shorter than the specified max. number of steps

due to missing a ax argument in plt.colorbar():

ValueError: Unable to determine Axes to steal space for Colorbar. 
Either provide the *cax* argument to use as the Axes for the Colorbar, 
provide the *ax* argument to steal space from it, or add *mappable* to an Axes.

(Python 3.10, Win10)

Error message: It is not currently possible to manually set the aspect on 3D axes
Proposed solution: Remove plt.gca().set_aspect('equal') from helper_functions2.py

Model.plot_history(increments=[0, 1, 3]) is ignored.

Probably remove this argument and always plot the total history?

see as_matrix()

Solution: replace as_matrix() with values.

Figures are outdated, i.e. 3d-plots have no arrow heads and the output seems outdated.

• create a config file environment.yml see a49964d

The setup of trusspy seems broken.

For now only 3D-input is possible but quite anything is prepared for 2D mode. replace all static "3" to self.ndim to get dynamic analyis dimension.

During function calls, several class Attributes are updated. Therefore some function definitions have "side-effects" to the model. They may generate Errors which are hard to debug.

As matplotlib provides no arrows in 3D mode by default, trusspy can't display arrows for force and coordinate vectors.

• remove the config argument (undeformed configuration should be shown for inc=0)
• don't allow force_scale=None (must be float)

Hi, I'd be grateful if you could help me figure out how should I assign A0 and E0, and generally, all variables which have been defined relatively when I use the excel sheet as inputs. Regards,
truss1.xlsx

The documentation is currently offline due to a rename of the default branch.

New docs will be deployed on readthedocs soon.

• Re-upload to readthedocs
• Re-add apidoc

I saw the Pycon 2016 talk from Nina Zakharenko about Memory Management in Python and at the 21:19 min, she introduced the dunker slots attribute to define the attributes. Because with that, you can't assign at runtime new attributes to the class instance. This reduces the memory usage and improves performance.

To reduce boilerplate, there is also the possibility to use @dataclass(slots=True) as shown in this video, see also the python documentation → https://docs.python.org/3.10/library/dataclasses.html

it is ok that it is basically a copy of the first solution but the displacements should be the initial displacements U0 (undeformed increment). Increment 0 exists only for internal usage and for plotting the undeformed model.

Follow-Up of #10 .

Add an option to draw supports (roller, pinned) inside the model plot. As TrussPy is 3D-based this seems a quite complicated task: Which symbols should be used? The Classic symbols in each direction? Which plane should be used to draw the symbols? Is it possible that the 2D plots are still projections of the 3D scene or are special considerations based on 2D/3D needed?

Title is self explaining.

Was wondering how to solve it. Any suggestion would be appreciated. Thank you so much!

Hi! I was easily managing to get trusspy running on linux - thanks a lot :) I'm trying to simulate some pretty simple static structures and I want to read out the individual element and reaction forces. I looked into a few of the object's properties - however the complexity of the data structure was a bit overwhelming and didn't find the forces :)

could you give me a hint where to look for the reaction forces for each node and the forces inside each element?

Hi, I was interested in using this library. However, when I tried running the example, an error showing 'Model' object has no attribute 'External Forces'

Remove all unnecessary lines of code, simplify as much as possible but do not change the API

The png's seem to be unordered if example 101 is executed on binder. On my local machine (Windows) everything is ok. Probably binder is running on Linux and files are sorted differently there. It is assumed that the gif generation is also broken if TrussPy is executed locally on a Linux machine.

Which units should be used for:

• Length: m ?
• Area: m² ?
• Force: kN ?
• E-modulus: kN/m² ?
• Degree: rad ?

So what units should the numbers I write in the functions have?

My question is whether I can choose whether to include geometric nonlinearities (as one can do with material nonlinearities).

Preliminary Work

• Run tests with tox

Tasks

• Automate publish on PyPI if a release is created
• Run tests and use codecov.io (needs preliminary tasks)

via pandoc. PDF also requires LaTeX. This is considered as an external task and shall not be part of TrussPy.
