      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.
