Anyone knows the value of the variable SMALL in fluent? I've written in my UDF #define SMALL 1.e-30; but when interpreted it just happeared a warming saying that SMALL already exists and it will be changed. I had looked at the fluent's manuals but I didn't find anything...Thank you.
If you have a Linux installation you can go in:
(where * and ? are relative to specific versions) and do:
grep -i -n "#define SMALL " *
which will tell you that SMALL is defined as 1e-10 in f_wall.h at the line 207 (in Fluent 14.5).
Why don't you just use mySMALL?
Thank you! Your answer helps me. Probably I'll use a different SMALL value from that of fluent.
