Python bindings to Frame3DD
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 parameterrigidcan 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.
$ python setup.py install
$ python test/test_frame.py
