Hello.
Today I solved a problem of mine with Else and Else If expression in cfd post. so I want to share it with you. The If ElseIf statement in CFD Post is:
if(condition, if(condition, true statement, false statement))
as you know the simple If is:
if(condition, true statement, false statement)
so, you can make loops. Here is a sample:

if(X>0[m],atan(Y/X),if(X<0[m],atan(Y/X)+180[deg],90[deg]))

Hope it will be useful
