Description:
WISDEMpyFrame3DD 1.1.1
pyFrame3DD
Python bindings to Frame3DD
Documentation
Browse the documentation for Frame3DD. This is a Python wrapper to that code with the following modifications:
Elimination of all input/output files in favor of direct variable passing
Arbitrary stiffness values can be passed in (rather than only rigid or free). ReactionData(node, Rx, Ry, Rz, Rxx, Ryy, Rzz, rigid=1) takes as input the optional parameter rigid (defaults to 1, which is what Frame3DD uses), which defines what number in the reaction inputs corresponds to a rigid connection. If a user wants to input spring constants in Rx, Ry, etc. those will be used directly in the stiffness matrix. The parameter rigid can then be set to anything else like -1.
Frame3DD allows inclusion of concentrated masses but they only affect the modal analysis. In pyFrame3DD they also affect the loads.
There is example code that shows usage contained in examples/exB.py. This follows example (B) Pyramid Frame contained on the Frame3DD home page.
Prerequisites
pyFrame3DD requires a C compiler
Install (as a library)
For detailed installation instructions of WISDEM modules see https://github.com/WISDEM/WISDEM or to install pyFrame3DD by itself do:
$ pip install WISDEM-pyFrame3DD
Install (from source)
If you would like to build the project locally from source for easier access to the underlying methods and tests, do:
$ git clone https://github.com/WISDEM/pyFrame3DD.git
$ cd pyFrame3DD
$ pip install .
If developer/editable mode, do the same git clone step, but on install do:
$ pip install --no-build-isolation -e .
The --no-build-isolation option is important per Meson guidelines.
Unit Tests
$ pytest test
