Dear community,

 

I have two problems about this program

1. How to fix the problem of Mechanical APDL Product Launcher (BATCH) when I run loop process in Loadstep. During the running of LARGE DISPLACEMENT ANALYSIS and it has UNCONVERGENT and then the program is stop working and it show about this

I add some code and attach file code Name: CODE1 and start at LN481.

ALLSEL,ALL
ANTYPE,STATIC,NEW
PSTRES,ON
NLGEOM,ON  
SSTIF,ON
NCNV,2
PT_LD_JOINT1=(NJOINT-1)/2+1
loadsteps=120
*DO,L111,1,loadsteps,1
         *IF,L111,LT,7,THEN
              F,CHORD_NODE_NUM1(PT_LD_JOINT1,2),FY,-0.1*PCRMODEL%II%*L111
         *ELSEIF,L111,LT,11,THEN
              F,CHORD_NODE_NUM1(PT_LD_JOINT1,2),FY,- (0.6*PCRMODEL%II%+0.05*PCRMODEL%II%*(L111-6))
         *ELSEIF,L111,LT,21,THEN
               F,CHORD_NODE_NUM1(PT_LD_JOINT1,2),FY,-(0.8*PCRMODEL%II%+0.01*PCRMODEL%II%*(L111-10))
         *ELSEIF,L111,GT,20,THEN
               F,CHORD_NODE_NUM1(PT_LD_JOINT1,2),FY,-(0.9*PCRMODEL%II%+0.005*PCRMODEL%II%*(L111-20))
         *ENDIF
LSWRITE,L111
*ENDDO
LSSOLVE,1,loadsteps,1

2. If I want NODE1 that is support move to direction UY. It have distance equal NODE2 when Loadstep running every STEP on LARGE Displacement Analysis. How I can do and what I need to using command ?

I attached file Name CODE1 for LARGE Displacement Analysis start at LN481.

 

Thank you very much for your help.
