Framat

---

FramAT (Frame Analysis Tool) is a tool for FEM beam analyses. Currently FramAT provides a full implementation of 3D Euler-Bernoulli beam theory, also known as standard engineering beam theory.

Installation

pip install framat

To update an existing installation:

pip install --upgrade framat

Example

FramAT provides a user-friendly, easy-to-read Python interface which can be integrated in complex workflows. Try it yourself. Just import the Model object from the FramAT library, and define your model:

from framat import Model

model = Model()

mat = model.add_feature('material', uid='dummy')
mat.set('E', 1)
mat.set('G', 1)
mat.set('rho', 1)

cs = model.add_feature('cross_section', uid='dummy')
cs.set('A', 1)
cs.set('Iy', 1)
cs.set('Iz', 1)
cs.set('J', 1)

beam = model.add_feature('beam')
beam.add('node', [0, 0, 0], uid='root')
beam.add('node', [1, 0, 0], uid='corner')
beam.add('node', [1, 1, 0], uid='tip')
beam.set('nelem', 10)
beam.add('material', {'from': 'root', 'to': 'tip', 'uid': 'dummy'})
beam.add('cross_section', {'from': 'root', 'to': 'tip', 'uid': 'dummy'})
beam.add('orientation', {'from': 'root', 'to': 'tip', 'up': [0, 0, 1]})
beam.add('point_load', {'at': 'corner', 'load': [0, 0, -1, 0, 0, 0]})

bc = model.set_feature('bc')
bc.add('fix', {'node': 'root', 'fix': ['all']})

pp = model.set_feature('post_proc')
pp.add('plot', ['undeformed', 'deformed', 'nodes'])

model.run()

⚠ Note

Starting from version 0.3.2 to 0.4.0, the interface for FramAT has changed completely to a more user-friendly Python API. Please refer to the documentation for updated instructions and examples.

Older development versions can still be found under the releases (not recommended). The current interface is still under development.
