v1.5.0

This release includes multiple breaking changes that had been building up in the backlog. Hopefully these changes will now make various parts of anaStruct make more intuitive sense, but some minor updates may be required to scripts or APIs that use this package as a result.

Breaking Changes

1. Definitions of "y" and "z" axis directions have been made fully consistent throughout all user-facing and internal code. The "y" axis is now always the vertical, in-plane axis, and the "z" axis is now always the out-of-plane axis. Changes generally do not affect inputs, but several outputs are affected. For example, "Ty" and "phi_y" are now "Tz" and "phi_z", respectively.
2. insert_node() now splits up an element in-place, rather than re-creating the entire system. As a consequence, the function will now no longer lose your loads and supports! While technically breaking behaviour, this is probably also more intuitive behaviour.
3. get_element_result_range() now by default returns the maximum absolute value of the given unit along the entire length of each element, rather than the first mesh value. A new optional parameter called minmax can customise this behaviour to alternatively return the "min", "max", or "both".
4. get_node_results_system() and get_node_displacements() now return a list of dictionaries rather than a list of long tuples by default or when node_id=0. This now mirrors the behaviour of the get_element_result*() functions, and should be easier to read.

What's Changed

• Return min/max values with get_element_result_range() by @smith120bh in #212
• Return a list of dicts from get_node_results_system() & get_node_displacements() by @smith120bh in #213
• Rewrite insert_node() to manipulate the existing system by @smith120bh in #215
• Correctly split triangular q-loads in insert_node() by @smith120bh in #216
• Remove orphaned nodes in remove_element() by @smith120bh in #217
• Fix show_results() plotting by @smith120bh in #218
• Clean up all y and z coordinates by @smith120bh in #219

Full Changelog: release-v1.4.4...release-v1.5.0

v1.4.4

This update is primarily a maintenance release, though with a couple notable additions:

• Location inputs have been unified such that every function now expects the same "VertexLike" input - which includes our existing Vertex object, as well as any Sequence (list or tuple) or two numbers.
• New function add_sequential_elements() has been added - which is very similar to the existing add_element_grid(), but with a more accurate name and able to accept coordinates as Vertex or VertexLike objects, to match with coordinates inputs on other functions
• All functions throughout the codebase now have full docstrings, which should make both using the functions (if you're using an IDE) and contributing to the anastruct code easier
• VS Code configuration has been thoroughly updated, to hopefully make it easier than ever to help contribute to the anastruct codebase! :-)

What's Changed

• Add EA and EI values to element creation documentation by @ajossorioarana in #189
• Update VS Code Config to recommend extensions by @smith120bh in #193
• Include github actions in dependabot by @smith120bh in #196

v1.4.3

This is exclusively a bugfix release, correcting a regression in the find_node_id() function, fixing the handling of pinned nodes that have only one element connected to them, and adding some meaningful error-handling to non-integer node and element ids.

Full Changelog: release-v1.4.2...release-v1.4.3

v1.4.2

This release represents few changes in the actual user-facing package, but significant updates to validation testing, packaging practices, and typing. Specifically:

• There is now a full suite of automated pytest validation tests verifying that anaStruct does, in fact, give the same results as Euler-Bernoulli analytical equations. Thank you to all the new contributors who helped add these tests!
• The file structure and package definitions in anaStruct have been updated to modern best practices, including swapping from a setup.py file to pyproject.toml, updating all the GitHub workflows, and adding some default/recommended VS Code configuration to help any contributors to this package work more easily!
• Full type checking has been implemented throughout anaStruct, and a py.typed marker file has been added for anyone using anaStruct as a library (you can remove those # type: ignores on your anastruct imports now!) In typing everything, a few scattered bugs were also identified and fixed (nothing that would have given a wrong result, but several little things that would have caused error messages), especially around setting loads on multiple elements at once.

Full Changelog: release-v1.4.0.1...release-v1.4.1

v1.4.0.1

Very minor update to avoid an error message being over-issued.

What's Changed

• Don't throw inclined roller error if angle is a multiple of 90 degrees by @smith120bh in #114

v1.4.0

Notes:

• This version has dropped support for Python 3.7! That is primarily due to the latest version of matplotlib also dropping support. You should still be able to install a headless version of anaStruct in Python 3.7 - but tests will no longer be automatically run against Python 3.7, so use at your own risk.
• If you wish to install anaStruct with plotting capability, you now need to explicitly install it using pip install anastruct[plot]. Alternatively, you can now install a headless version of anaStruct using just pip install anastruct.

What's Changed

• Move matplotlib to extras_require, to make headless installs possible by @smith120bh in #112
• Set Minimum Python version to 3.8 & Bump matplotlib from 3.0.3 to 3.6.2 by @dependabot in #100

Full Changelog: release-v1.3.4...release-v1.4.0

v1.3.4

Note: This will be the final release to support Python 3.7, and the final release in the v1.3 line. It concludes fixing all outstanding bugs.

What's Changed

• Only assert non-None axial element results for truss elements by @smith120bh in #109
• Add error message if point load applied at inclined roller by @smith120bh in #110
• Bump pylint from 2.15.9 to 2.15.10 by @dependabot in #111
• Fix reactions and nodal results in load combinations by @smith120bh in #113

Full Changelog: release-v1.3.3...release-v1.3.4

v1.3.3

What's Changed

• Create CITATION.cff by @someparsa in #97
• Fix bug with specifying direction of q_load by @smith120bh in #106 (thanks, @ghylander!)
• Fix Q-loads in LoadCases by @smith120bh in #107 (thanks, @RichardWhitfield!)
