ABAQUS-UMAT

等几何分析MATLAB程序包,有着丰富的例子,其中fem包内为传统的拉格朗日插值有限元, iga包内为nurbs插值的等几何有限元(This is the README file for the Isogeometric Analysis (IGA) Matlab code. The code supports one, two and three dimensional linear elasticity problems. Extended IGA for hole, inclusion and crack modelling is also implemented.)

说明：  此是多峰函数MATLAB程序，多峰函数在解决多峰曲线问题中经常会用到，有此程序代码可以省去很多麻烦。(This is a multi-peak function MATLAB program, multi-peak function, multi-peak curve in the settlement of the question is often used, there is such a code can save a lot of trouble.)

说明：  C语言编写8个点的FFT程序,在WINTC上编译通过(C language 8 point FFT procedures WINTC compiled through)

crackprop_modeI_lefm_xfem_cpe4，ABAQUS基于线弹性断裂力学的扩展有限元法实例。(crackprop_modeI_lefm_xfem_cpe4 ABAQUS based on linear elastic fracture mechanics extended finite element method instance.)

本算法是基于数值计算中的SQP编写的MATLAB程序。非常实用的一个小程序。(This algorithm is based on the numerical calculation of SQP written MATLAB program. Very practical one small program.)

基于有限体积法的naca0012翼型的无粘绕流计算(Calculation of airfoils based on the finite volume method naca0012 inviscid flow around)

邻带计算，高斯正反算，可以实现测绘系统内简单的转换计算，但是是基于80坐标系统的。(failed to translate)

说明：  借助python3计算偏微分方程组，并作出相应图形，代码简单易懂，方便修改(Calculate partial differential equations)

施威德勒球壳在ansys中的建模分析，APDL语言(Of Schwedler shell modeling in ansys, APDL language)

国外的地震有限元程序，美国伯克利大学的，非常经典(Earthquake abroad finite element program, the United States Berkeley, very classic)
