1  develops from the pure structure mechanics computation to solves many physical fields question finite element analysis method most early is comes from the structure matrix analysis development, gradually promotes to the board, the shell and the entity and so on the continual body solid mechanics analysis, the practice proved this is one extremely effective numerical analysis method。 Moreover the or etically also already proved, so long as uses in to be separated solution object the unit enough to be small, the obtained solution may enough approach to the precise value。

   Therefore the recent years finite element method has developed question the and so on hydromechanics, temperature field, electricity conduction, magnetic field, transfusion and sound field solution computation, recently developed solves several inter disciplinary studies。 the questions。 For example when the air current flows a very high iron tower to have the distortion, but the tower distortion in turn affects to the air current flows。 This needs to use the solid mechanics and the hydrodynamics finite element analysis finally overlapping iteration solves, namely so-called " Flows solid coupling " Question。 

2  Progresses from the solution linear project question to the analysis non-linear problem along with the science and technology development, the linear theory already by far could not satisfy the design there quest。 For example in construction profession high-rise construction and great span hanging bridge appearance, request consideration geometry non-linear problem and so on structure big displacement and big strain; Astronautics and power engineering high temperature part existence thermal deformation and thermal load, also must consider the material the non-linear problem; Such as the plastic, the rubber and the compound material and so on each kind of new material appearance ,only depends on the question which the linear computation theory is insufficient to solve meets, only has uses the non-linear finite element algorithm to be able to solve。 It is well known, the non-linear value computation is very complex, it involves to the very many special mathematics question and the operation skill, thanks the general engineering technical personnel to grasp very much。 Has spent massive specialty and so on manpower and investment development such as MARC, ABQUS and ADINA for this recent years overseas some companies to solution non-linear problem finite element analysis software, and widely applies to the project practice。 These software common characteristics are have the highly effective non-linear solution as well as rich and the practical non-linear material。 Definitely。

3  The enhancement visible pretag e modelling and the post positioned data processing function early time finite element analysis software research key lies in infers new high efficiency solution method and the high accuracy unit。 Along with the numerical analysis method gradually consummation, the computer operating speed rapid development, the entire computing system uses in to solve the operation in particular the time more and more few, but the data preparation and the operation result performance question day by day is actually prominent。 On the present project workstation, solves to contain 100,000 equations the finite lement models only to need to use several dozens minutes。 But if establishes this model with the manual way, then the rehandling massive computed result must use several week-long time。 May not exaggerate said, engineer calculates a project question when the analysis has 80% above the energy all to spend in the data preparation and the result analysis。

Therefore the present nearly all shangye finite element software all has the function very strong pretage modeling and the post positioned data processing module。 Is emphasizing " Visible " Today ,very many procedures have all established to user extremely friendly GUI (Graphics User Interface), enables the user direct-viewing fast to carry on the grid automatic pision by the visible graphic mode, the production finite element analysis needs the data, and the massive computed result will reorganize the distortion chart, the equivalentd is tribution  cloud chart according to the request, will be advantageous for the extreme value search and needs the data to tabulate the output。
