Global variables were initialized to 0

Mars35 · February 16, 2023, 12:34

Hi guys,

I have define_init to read a text file and store my data in an array (global variable). This was working fine. In the same C file, I also used define_profile such that as long as my position coordinate matches, I would use the velocity at that coordinates. However, it was not working. Because I found out the arrays that stored my coordinates data was 0. I went to check on post on C program which I found the static and global variables were initialized to 0.

Is there other ways that I can keep my values in array? Thank you.

Hi guys,

The problem was solved without defining a global variable. However, it would still be great if I could learn how to update the values for global variable in the UDF. Thank you for reading this post and have a nice day!
