Can you elaborate on what problem you are facing in your APDL script that you have posted?

! I have an array equal to 76rows and 4 columns, the first column of which has areas . I want to read the first column of that array element by element , so that when the first area is selected I can select the lines and the keypoints for that area using LSLA and KSLL, and input those keypoints for mapped meshing of that particular area, then proceed with the next area and reapeat the same things for the entire first column.

This is the code which I have written

!ANUM_A has the areas in the first column

*DIM,ANUM_C,ARRAY,acount,5

*vfun,ANUM_C,copy,ANUM_A

CMSEL,S,TOPAREA,AREA

APLOT

*do,i,1,acount

asel,s,area,,ANUM_A(i,1)

lsla,S

LPLOT

ksll,S

KPLOT

A = KPINQR(0,13)

KNUM = 0

*DO,J,1,A

KNUM=KPNEXT(KNUM)

*SET,ANUM_C(I,J+1),KNUM

*ENDDO

AMAP,ANUM_C(I,1),ANUM_C(I,2),ANUM_C(I,3),ANUM_C(I,4),ANUM_C(I,5)

*enddo

I think part of the answer to this question is given in my answer to your previous question regarding how to set up the array properly ("How to SELECT THE keypoints associated with area numbers in APDL?"). So, I refer you to that answer. Once you have the array filled with desired data (following the variable names in the code I wrote in the previous answer), you can simply do this to select lines and KP associated with each area:

*DO,I,1,A_NUM

ASEL,S,AREA,,AREA_LIST(I,1) !---SELECT ONE AREA

LSLA,S !---SELECT LINES ASSOCIATED TO THE AREA

KSLL,S !---SELECT KP ASSOCIATED TO THE SELECTED LINES

!----NOW YOU CAN PERFORM WHAT Y7OU NEED WITH SELECTED KP

ALLSEL !---SELECT EVERYTHING

*ENDDO

@ Mahdi...Thanks for your input

https://www.researchgate.net/post/How_to_select_only_those_keypoints_at_the_outer_vertices_of_areas_in_APDL?_ec=topicPostOverviewAuthoredQuestions&_sg=cR4GoTHQAdElqbXsQRf3NfilvVp67BSYoOaxFt2HHdkEqVuvuDemzKyHmykiNbhuIcQx1rkXIXG6Ft-k.cbkTQ7QHG1eFBjalIOByaPE3Vzh9tXKRwrdnGJxLc4NKnWaJFpyoq57Lkn96vATr06Dzr6tUPfWwGzglwTrr3AU

In the above link some of my areas has 5 keypoints and I only want to select the keypoints which are at the vertices, so the above mentioned code will not work for keypoints other than 4. I have to somehow select only those keypoints which form the area and drop the midside keypoints.

I agree with Claudio Pedrazzi

I find that the more automation needed the more complex the code gets, and we humans are under rated :D
