In their own words
OpenLSTO
OpenLSTO is open-source C++ software for structural topology optimization using a level set method. It seeks to minimize compliance, or maximize stiffness, within a volume constraint in a two-dimensional design domain. Developed and maintained by researchers at UC San Diego and Cardiff University, the described first light version is limited to that 2D problem. It runs through command-line arguments in a terminal; simple serial cases without external libraries can be compiled and executed with a C++ compiler. OpenLSTO produces.vtk solution files that ParaView can read, so users need a data visualization tool for post-processing. The project favors in-house components where possible and is available under the Apache 2.0 license. It runs on Linux, macOS, and Windows, with repository-clone and ZIP download options. The software is free: the OpenLSTO plan is free. The project says expanded capabilities using externally provided software are planned for a more advanced version.
