thank you for your reply. Indeed, generated input file is full of strings.
I went though FLAIR’s manual and I resolved this issue (and many more . . .). Thank you again. But in the end I getting different error message:
*** To many terms in parenthesis expansion ***
*** Execution terminated ***
I guess it’s because my VOID region, which is quite complicated.
I am not sure, how can I avoid building such structures. Is there any general recommendation or strategy, how to build a bit more complicated geometries? I also try to run test simulation with “online evaluation” by setting the variable “Paren”, but it also crushed, but without generated files.
Thank you any help.
