creating path with APDL

[SKJoe]

Hello all,

Consider a analyses (let say 100) of square with different mesh sizes. I want to know some quantities on one edge - it means display them along a path. So i need to develop a macro, which is capable to create a path along the edge for different mesh sizes.

does anyone have an idea how to do that ?

I have already created one macro, which I suppose is written correctly, but it didnt work...

can anyone help me ?

sorry for my english

Regards,
Lubo



A=0.020 ! the smallest length of elements (spacing of nods are not uniform...)
B=1.400*2/A

*DIM,C,,(B+1)
*VFILL,C(1),RAMP,0,1

*DIM,PATH_01,,(B+1) ! array to store numbers of nodes...

*DO,T,1,(B+1),1

D=C(T)*B-A*0.25
E=C(T)*B+A*0.25
F=C(T)+1

NSEL,S,LOC,X,+2.620,+2.630
NSEL,R,LOC,Z,-0.010,+0.010
NSEL,R,LOC,Y,D,E

*GET,G,NODE,0,COUNT

*IF,G,EQ,O,THEN
PATH_01(F,1,1)=0
*ENDIF

*IF,G,NE,O,THEN
*GET,NOD,NODE,0,NUM,MAX
PATH_01(F,1,1)=NOD
*ENDIF

ALLSEL,ALL

*ENDDO

Hi,

the Problem is, you must sort the nodes in the nodes aray about the position along the path.
