Z88 is a free finite element software package available for Microsoft Windows, Mac OS X and Unix/Linux computers. Versions are available for 32-bit and 64-bit operating systems. There are two versions of Z88 available: the Open Source Version Z88 V14 (without preprocessing) and the freeware system Z88Aurora (pre-&post processing). Now Z88 features static calculations in mechanical engineering and building & construction industries. Z88Aurora V2 features frequency analysis, thermo-mechanical analysis and large deformations. The complete program is freeware, small, easy to use and built for the use on desktop computers with different operating systems and due to users' feedback constantly being improved. Z88 is coded in ANSI-C. ==Development and Contents== Z88 is developed and maintained by Professor Dr.-Ing. Frank Rieg holding the chair of engineering design and CAD at the University of Bayreuth in Germany and his crew. The Open Source Z88 V14 features over 24 different types of finite elements (2D: truss, beam, torus, plane stress elements; 3D: truss, beam, tetrahedron with 4 or 10 nodes, hexahedron with 8 or 20 nodes) a graphical interface and a plot program. Input and output are transparent text files. Several solvers (Cholesky, SICCG, SORCG, Sparse-solver) with multi domain feasibility are included. Since 2009 a new pre- and post processor called Z88Aurora is developed by a team around Prof. Rieg and was released in June 2010. Z88Aurora uses the technology of Z88 V14.0 combined with an intuitive user prompting (contains boundary conditions, several free FE-mesher, material database with data fitting). Additional features of Z88Aurora V2 compared with Z88V14: * import of fe data: ANSYS, NASTRAN, COSMOS, ABAQUS * import of geometry data: STL, STEP * different free and mapped mesher with adjustable options (tetrahedron, hexahedron) * picking function for loads and constraints (pressure, force, displacements) * multi core parallel solver * detailed documentation (user guide, videos, theory guide, ready-to-run examples) File:Z88aurora snap.png|Z88 Aurora File:Z88aurora SPIDER help.png|Workflow File:Programsnapshot Z88V14.png|Snapshot open source program Z88 V14 File:Programsnapshot Postprocessor Z88 V14.png|Postprocessor Z88 V14 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Z88 FEM software」の詳細全文を読む スポンサード リンク
