[HELP] Value range of a returned variable
Hi there, It's me again.

Since I am still simulating a laser fusion melting process, I ran into a completely new problem.

The heat sources I use for my calculations are computed using a UDF.
It looks like this:

...lots of code...
return source;

Now here is the thing: the returned variable ("source" in this case) has a limited range. Apparently it seems to be restricted to the range of a signed long integer -2,147,483,648 to 2,147,483,647). :eek:
All variables were initialized as "double" and I am running the case in double precision, so the problem is definitely the range of the returned variable.

Now the intensities of a laser beam are very high, so I need higher values of the returned variable.

What can I do?
