Software
Abaqus Color spectrum – git
This creates several color gradients in Abaqus visualization. The colormaps are taken from Matplotlib. Note that one should never use the default colormap in Abaqus for figures (read more here)
Abaqus Truss / Beam analysis – git
This script takes as input a set of nodal coordinates, connectivities (which also contain the beam information, i.e. E, A, I), boundary conditions and creates an Abaqus model with these defined. The analysis can be set to run automatically.
Matlab truss analysis (linear and nonlinear) (Coming soon)
This Matlab script takes as input a set of nodal coordinates, connectivities (which also contain the beam information, i.e. E, A, I), boundary conditions, calculates the stiffness tensor, and then the deformation vector.
Bar network STL generator (Matlab and python) – git
Instead of using the native mesher for cylindrical bar network, which will create large file sizes, this code takes the set of nodal coordinates, connectivities and area, as well as the polygon count, and outputs a STL file (ascii or binary) with much smaller file size.
Gcode generator for material testing – git
Generating only fill on the x-y plane oriented at a fixed orientation w.r.t. the x axis, replicated in the z direction. The xy pass overlap and the z pass overlap can be controlled independently.
Conformal mapping based microstructure design – git
Calculate the scaling for 3D to 2D shape transformation in Grasshopper. Then overlaying a grid and assigning unit cell microstructure to each grid element.
Chebchev net generator (Coming soon)
Cloth a 3D surface using two groups of orthogonal lines.
