Hi,
I defined a list in TUI using the command (rp-var-define 'my-id-list '(1,2,3) 'list #f). I then tested it in UDF using the following code:

#include"udf.h"
#include"var.h"

DEFINE_ON_DEMAND(test)
{
int n;
int i=1;
n=RP_Get_List_Length("my-id-list");
Message0("the length of list:%d",n);
}

but it went wrong

RP_Get_List_Length: Unable to get length of my-id-list.

. I don't know why

I found the reason, I forgot to parallelize the code. So I wonder after which version it doesn 't need to be parallelized

another question:
In Version 2023R1, it shows "the length of list:0". But in Version 19.2, it is normal by showing "the length of list:3". This really puzzles me.

probably, length =0 is wrong, isn't it?

Yes,it is wrong. In Fluent 19.2, the UDF is able to correctly recognize the list defined by RP. However, in the 2023R1 version, it can not recognize the list correctly, but other RP variables such as a single variable of real type can be recognized.
