ansys怎样通过修改命令流原有路径来改变结果

ansys怎样通过修改命令流原有路径来改变结果，比如将仿真的路径2内壁面和路径3的外壁面交换，先仿真外壁面在经行内壁面的仿真。

!路径2 内壁面
nsel,s,loc,x,0
nsel,r,loc,z,0,2*ro
nsel,r,loc,y,ri
P_Name='path2'

seleNN=NDINQR(0,13) !获取节点总数
*DIM,Path_Node,ARRAY,seleNN,2,
*VGET,Path_Node(1,1),NODE,1,NLIST
*do,i,1,seleNN
Path_Node(i,2)=(nz(Path_Node(i,1)))*1000
*enddo
*MWRITE,Path_Node,%P_Name%loc,txt,,JIK,2,seleNN
(F10.0,F15.3)
tsj
*set,seleNN,,
*set,Path_Node,,


!路径3 外壁面

lsel,s,loc,x,0
lsel,r,loc,y,ro
nsll,s
nsel,r,loc,z,0,2*ro
P_Name='path3'

seleNN=NDINQR(0,13) !获取节点总数
*DIM,Path_Node,ARRAY,seleNN,2,
*VGET,Path_Node(1,1),NODE,1,NLIST
*do,i,1,seleNN
Path_Node(i,2)=(nz(Path_Node(i,1)))*1000
*enddo
*MWRITE,Path_Node,%P_Name%loc,txt,,JIK,2,seleNN
(F10.0,F15.3)
tsj
*set,seleNN,,
*set,Path_Node,,
