Eddybj is on a distinguished road
I run into an error message when trying to compile UDF using Ansys 2022 R1 Fluent's built in compiler Clang. The error message is as follows,

uvdose_par.c(42,50): error: member reference base type 'void' is not a structure or union
par_fprintf_head(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,14);

It seems to indicate that line " par_fprintf_head(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,14);" of my code below has a problem. Here is part of the code of concern:

if (header)
if (NNULLP(thread))
par_fprintf_head(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,14);
par_fprintf_head(fp,"(%s %d)\n",plane->sort_file_name,14);

par_fprintf_head(fp,"(%10s %10s %10s %10s %10s %10s %10s"
" %10s %10s %10s %10s %10s %10s %10s %s)\n",

I am a bit puzzled and have no clues as to what could be wrong as the code was actually written in 2008 and was compiled successfully at the time. I wonder if anyone could shed me some light on this error and suggest a way to fix it. Many thanks.
