General-purpose structural analysis software "ASU/ISTR" for structure, heat transfer, and vibration.
A dedicated pre/post-processor that supports the practical use of the free solver FrontISTR, capable of large-scale analysis of various engineering problems such as structural, heat transfer, and vibration analysis.
ASU/ISTR has packaged the free general-purpose structural analysis software FrontISTR, developed by FrontISTR Commons (Representative Director: Professor Hiroshi Okuda, The University of Tokyo), into a Windows version with pre- and post-processing capabilities for easy use by anyone. - Covers the main features of FrontISTR - Equipped with a robust automatic solid mesh generation function that supports multi-part models, allowing for immediate analysis setup and execution once CAD data is provided. - The open-source solver can be used commercially at no cost, and license fees do not increase even for large-scale problems. - A basic material database is provided, supporting isotropic and orthotropic materials. - We also offer customization development of pre- and post-processing to fit your unique workflow. - Utilizes our GUI platform ASU/GROOVE, which has over 140 successful implementations. - Our company has members who are part of the FrontISTR solver development team, capable of addressing advanced technical requests, such as adding unique calculation routines to the solver.
