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);
else
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",
"X0","Y0","Z0",
"X","Y","Z","U","V","W","diameter","T","mass-flow",
"time","UV-Dosage","name");
}

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.

Hi Eddy,

I came across your post from a year ago concerning the UV Irradiation code from Sandia, which I'm also utilizing. Despite addressing several warnings, I've encountered the same persisting error you mentioned in your February 2023 forum post. Unfortunately, it seems your query went unanswered. I'm reaching out in the hopes that if you've made any progress since then, you might be able to assist me in resolving this issue. My project deadline is fast approaching, so your help would be immensely valuable. Thank you in advance for any assistance you can provide.

Best Regards,
Niall
