FrontISTR is a Windows and Linux PC cluster and:
(1) An open source structural analysis solver that can be used with massively parallel supercomputers, fex. the K computer.
(2) It is improved, maintained and promoted by FrontISTR Commons, a general incorporated association established within the University of Tokyo.
(3) It has been using in various industries such as automobiles, industrial equipment, precision equipment, and construction.
In the iterative solution method based on FrontISTR, parallel calculation is executed by domain division.
Therefore, there is no limit to the number of processors that can be used, and it is suitable for computers of various architectures.
Jupiter can mesh over 100 million nodes.
Also, you won't notice any performance degradation from larger models.
It has an assembly function that automatically joins faces from CAD Geometry by specifying tolerance.
You can easily combine products that are composed of many parts.
