Hi Guys

In my UDF i want to write some data in a file after some calculation in the macro DEFINE_EXECUTE_AT_END and then i want to read in the next step from this file in my macro DEFINE_EXECUTE_AT_END,
the problem is the data for writing is with long decimal, so for example the amount 0.00000000000015 is written as 0.0000000 in the .txt file, i am wondering that in the next step how does fluent read it ?
if treads it as zero how can i fix it?

thank you
Hamid

You can try to write your data into a file by using scientific notation for double data type. Here you can find more information about output format for printf/sprintf method.
