dktshell 0.1.1

Matrix-based structural analysis module for triangulated thin shells

Matrix-based shape sensitivity analysis for linear strain energy of triangular thin shell elements

Source code of K. Hayashi and R. Mesnil, "Matrix-based shape sensitivity analysis for linear strain energy of triangular thin shell elements"

Install

The module can be installed through PyPI using the following command on the command prompt window:

pip install dktshell

How to use

algo = dktshell.DKTAnalysis()
displacement,internal_force,reaction = algo.RunStructuralAnalysis(vert,face_tri,dirichlet,load,thickness=0.25,elastic_modulus=4.32e8,poisson_ratio=0.0) # Use this input for Scordelis-Lo roof example
strain_energy,strain_energy_gradient = algo.StrainEnergy_with_Gradient(vert,face_tri,dirichlet,load,thickness=1,elastic_modulus=1,poisson_ratio=0.25)

For more detailed example, please find example.py in the GitHub repository. The input structural models required to run example.py are stored in the structural_models folder.

Note

If you run Python program in a directory and import this module for the first time, it will take several minutes for just-in-time (JIT) compilation using numba. This JIT compilation requires only once, and you can smoothly import this module from the second time.
