This code package can be used to compute human understandable design rules for the inverse design of origami structures. The code is based on the Decision Tree-Random Forest method implementation from the sklearn package. The code will automatically track the splitting criteria and find the branch with the highest F-score. We show that this branch and the associated splitting criteria can provide useful information for the inverse design of origami systems. (See GitHub Link)

This is an open-access simulator that can capture the multi-physical behaviors in active origami structures. The package can capture the compliant crease geometry, inter-panel contact, and electro-thermal actuation of active origami. The package allows users to create sequence of loading onto the origami systems with arbitrary number and stacks of different loading methods. (See GitHub Link)

Estimating structural responses of isolated structures with large number ground motions. Capable of reading large number of ground motion records and analyze their impact on isolated structures automatically. Its results provides better insight into the impact of large ground motion variability on structural responses.
