STKO (Scientific ToolKit for OpenSees) is a powerful pre and post processor and cutting-edge data visualization tool for Opensees. By using STKO a user can create a Tool Command Language (TCL) input file for Opensees and an output file readable by its graphic interface. The user can customize and manipulate with a Python-based scripting interface the model input and output to create customized engineering demand parameters and output data.
We will soon be online with our new platform dedicated to STKO (Scientific Toolkit for OpenSees)
where all interested users can take part in our WEBINARS on the correct use of STKO software. For more information, write to our email address: info@asdeasoft.net
Post processing of shell results at gauss points and at through-the-thickness integration points (fibers).
Post processing of beam-column results by means of a fiber-section plot, that allows the user to visualize results such as strain/stress at each fiber of each gauss points of beam-column elements.
Meshing algorithms in STKO pre-processor. Global and local edge seed, unstructured and structured mesh algorithms, triangle/tetrahedron, quadrilateral/hexahedron, linear and quadratic interpolations.
Post processing of beam-column results by means of a gauss-point plot, that allows the user to visualize results such at each gauss points of beam-column elements.

… features advanced CAD modeling tools, import-export of common CAD file formats, geometry repair tools, and a comprehensive set of meshing algorithms.
… is easily customizable via a python-based scripting interface. So custom components can be easily specified and added to the standard document, to fit the end-user needs.
… can then produce input files for OpenSees with all the information inputed by the user.

… features all common visualization algorithms (edge/surface color map, volume rendering, iso-lines, iso-surfaces, vector plots, etc..). Post processing also includes advanced visualization algorithms for beam/column and shell elements equipped with discretized (fiber) cross sections.
… is easily customizable via a python-based scripting interface. Therefore, results can be estracted and manipulated using custom python-scripts, allowing the end-user to produce custom information.
Finally, STKO uses an efficient opensource third-party database library for storing results, the HDF5 database library. The MPCORecorder is a new recorder class for OpenSees that allows OpenSees to write results data in the format required by STKO.
All these features in one Software: STKO, a revolutionary visualization toolkit for Opensees
