May say domestic FEA software the development continuously revolves the PC platform to make the issue。 Compares successful and has (above comparatively multiuser 100) the finite element analysis system in the domestic development to have the Dalian technical Universit beijing mechanics department FIFEX95, Beijing University mechanics and scientific engineering department's SAP84, Chinese farm machine arcade my of science's MAS5。0 and Hangzhou automation technical institute's MFEP4。0 and so on。 But just like above-mentioned, the overseas very many famous finite element analysis company already formerly a year not spare a glanced to the PC platform transforms for craves the development, to the domestic FEA procedure development said developed the PC edition no longer to have the superiority, but should perform from following several aspects diligently:
1 Research developments solves the non-solid mechanics and the interdisciplinary studies。 FEA procedure passes through several dozens years research and the development, used in to solve the solid mechanics the finite element method and software already quite is mature, now studies the front question was the hydrodynamics, may compress and the compressible flow body not flow and so on non- solid mechanics and the interdisciplinary studies question。 Because domestic not similar function commercialized software, therefore overseas software sells extremely expensively。 In order to break this kind of monopoly aspect, we must develop have the independent copy right, use in to analyze the fluid and so on non- solid mechanics and interdisciplinary studies。 software。 Because the hydromechanics question far is much more complex than the solid, moreover very little has ready-made software to be allowed to profit from, therefore needs to invest the massive manpower and the funds。 This must have the country and the major industry group supports。
2 Developments has the Chinese characteristic the automatic modeling technology and the GUI development modeling technology and the GUI investment states the topic compared to front to have little many, but actually may greatly enhance FEA software the performance and the user receptivity, thus gets up the twice the result with half the effort effect。 The domestic many people did in this aspect have very worked, but because at that time PC machine on graph strut environment limited, therefore the development effect not really was all ideal。 In Windows has provided the OpenGL graph standard, for applied visible graph technology development GUI on PC machine to provide the powerful tool。 OpenGL is the high performance graph and the interactive ground view processing standard which now on international recognizes, applies three dimensional graph software which it develops deeply specialized technical personnel's cherish, at present in the world occupied the dominant position the computer company all to use this standard。 Just like front states, in recent years overseas had the FEA procedure has abandoned simulation software, directly developed the finite element procedure in the Windows platform。 The Hangzhou automation technical institute 1997-1999 year uses the OpenGL graph standard and corresponding Visual C++ and so on programs the tool, successfully has developed set of visible finite elements routine packages on PC machine。 It can direct-viewing pass to " Menu" " Window " " Dialog box " With " Chartsign " And so on visible graph picture and mark operation, automatically establishes the finite element analysis model, and by interactive side Buddhist ritual procedures realization computed result visible processing, thus may greatly enhance limitedly raises the analysis the efficiency and the accuracy, also is advantageous for the user to study and to grasp。
3 With had the our country independent copyright front the CAD software integration already to say, now a finite element method important characteristic is and the CAD software seamless in the gration。 FEA procedure voluntarily develops which as our country, first must consider and our country independent copyright CAD software integration。 Because the finite element analysis mainly uses in the shape quite complex spare part, therefore must with have the three dimensional modeling function and the CAD software integration, causes the design and analysis in close integration with, merges in tone organic whole。
