如何编写ANSYS 静力分析程序

给你一个程序：
/PREP7
/TITLE, VM1, STATICALLY INDETERMINATE REACTION FORCE ANALYSIS
C*** STR. OF MATL., TIMOSHENKO, PART 1, 3RD ED., PAGE 26, PROB.10 ! 把注释放在文件中

ANTYPE,STATIC ! STATIC ANALYSIS 可以在模型创建过程中和计算求解过程中

ET,1,LINK1
R,1,1 ! 截面面积，必须输入，这里没有预应力，CROSS SECTIONAL AREA (ARBITRARY) = 1 截面积
MP,EX,1,30E6

N,1
N,2,,4
N,3,,7
N,4,,10
E,1,2 ! DEFINE ELEMENTS
EGEN,3,1,1

D,1,ALL,,,4,3 ! 约束BOUNDARY CONDITIONS AND LOADING
F,2,FY,-500 ! 施加力
F,3,FY,-1000
FINISH

/SOLU
OUTPR,BASIC,1 ! Basic quantities (nodal DOF solution, nodal reaction loads, and element solution) (default)
OUTPR,NLOAD,1 ! Element nodal loads. When nonlinear stabilization is active, the stabilization force/moments are also printed
SOLVE
FINISH
