Hi all, I’m wondering if we can use APDL commands under “Analysis Settings” to automate the process of inputting data for each time step, instead of doing it manually. Would this be more efficient?
<\/p>\n

This is my current script:<\/p>\n

! Define the temperature values for each cycle (2400 seconds cycle)<\/div>\n
*DIM,TEMP_ARRAY,ARRAY,5,1<\/div>\n
TEMP_ARRAY(1) = 0   ! Temperature at 0 seconds<\/div>\n
TEMP_ARRAY(2) = 0   ! Temperature at 600 seconds<\/div>\n
TEMP_ARRAY(3) = 125 ! Temperature at 1200 seconds<\/div>\n
TEMP_ARRAY(4) = 125 ! Temperature at 1800 seconds<\/div>\n
TEMP_ARRAY(5) = 0   ! Temperature at 2400 seconds<\/div>\n
 <\/div>\n
! Loop over each of the 400 steps (100 cycles total)<\/div>\n
*DO,I,1,400<\/div>\n
    ! Calculate the index in the temperature array (cycles every 5 steps)<\/div>\n
    INDEX = MOD(I-1,5) + 1<\/div>\n
    <\/div>\n
    ! Apply the temperature at the current step<\/div>\n
    ALLSEL,ALL<\/div>\n
    SF,ALL,CONV,TEMP_ARRAY(INDEX)<\/div>\n
*ENDDO<\/div>\n

Since I have input some data via GUI, I am wondering whether APDL commands will overread what I have input manually. Any suggestions would be appreciated!
