opstool: Pre-Processing, Post-Processing, and Visualization for OpenSeesPy and OpenSees
opstool is a powerful and user-friendly package designed to simplify and enhance structural analysis workflows
with OpenSees and OpenSeesPy.
It provides advanced tools for preprocessing, postprocessing, and visualization, making structural simulations more efficient and accessible.
Installation
The package is still under development.
To use, install opstool from opstool-PyPI:
pip install --upgrade opstool
The restriction on the python version mainly depends on openseespy,
it is recommended that you use Miniconda or Anaconda Distribution to avoid library version incompatibilities.
After installing, open Anaconda Prompt to execute the following code:
conda create -n opensees python=3.12 numpy scipy pandas xarray notebook matplotlib
conda activate opensees
pip install openseespy
pip install opstool
- The first line of code will create an environment called
openseesand install Python 3.12 and libraries such as numpy, scipy, pandas, xarray, notebook, matplotlib, etc. - Please use
conda activate openseesto activate the environment, and then you can install various third-party packages in the environment, such aspip install openseespyandpip install opstool. - You can also install the packages from anaconda / packages, such as
conda install conda-forge::scikit-learn.

For v1.0.20 and earlier versions See https://opstool.readthedocs.io/en/v1.0.20/
[!TIP] Since an opstool version v1.0.1, the API and features have undergone significant changes and upgrades. As a result, it feels more like a new library, and you should take some time to familiarize yourself with the new interface usage.
