【ansys基本建模算例】带法兰油缸的有限元分析，计算相关应力即变形([Examples] basic modeling ansys finite element analysis with flanged cylinder, calculating the stress that is associated deformation)

分维反映了复杂形体占有空间的有效性，它是复杂形体不规则性的量度。它与动力系统的混沌理论交叉结合，相辅相成。它承认世界的局部可能在一定条件下或过程中，在某一方面（形态，结构，信息，功能，时间，能量等）表现出与整体的相似性，它承认空间维数的变化既可以是离散的也可以是连续的，进而拓展了视野。(Fractal dimension reflects the validity of space occupied by complex bodies, which is a measure of irregularity of complex bodies. It combines with chaos theory of dynamic system and complements each other. It recognizes that the part of the world may be similar to the whole in certain conditions or processes (form, structure, information, function, time, energy, etc.). It recognizes that the change of spatial dimension can be discrete or continuous, thus expanding the horizon.)

说明：  朴素贝叶斯算法，以函数形式实现，花了一个上午的时间(Naive Bayes algorithm, in order to function the form of implementation, a morning flower time)

FLUENT udf 更改S-A 湍流模型源项的程序(modify turbulence model S-A)

用于有限元软件Abaqus分析材料断裂的粘结区模型（CZM）子程序，由著名学者高彦飞编程，具有很高的参考价值。(ABAQUS allows the addition of a variety of user subroutines. We define a user element by UEL. Information of element and nodal displacements can be obtained from ABAQUS, and we update the stiffness matrix and the residual vector following the cohesive zone law. More coding details can be found in ABAQUS manual.)
