Dear Community,

I have been practicing a thermal modelling routine in APDL.

The modelling includes a repetition of a certain set of commands and scalar parameters in a cycle. I got it through the *DO and *IF commands. However, the code is getting extremely lengthy and time taking (for compilation) to set *IF command for every *DO parameter value (Like *DO is running from 1 to 100). But, in actuality the scalar parameters on change for the even and odd values of the *DO parameter.

The code I want goes like this (but it is not working)

!-----------------------------------------------------------------------------

*DO,ii,1,100,1

*IF,ii,EQ,'EVEN',THEN

X = 1

*ELSEIF,ii,EQ,'ODD',THEN

X = 2

*ELSE

*ENDIF

!--------------------------------------------------------------------------

If anybody knows how to set this working, please help

There are probably multiple approaches that will work. One approach might be to use the MOD(x,y) function. to find the remainder. Something like:
x1 = mod(ii,2) ! place immediately after *DO command
If ii is an even number; then x1 would be equal to zero
If ii is an odd number, then x1 would be equal to 1
You can then use x1 in the *IF statements
