Goodmorning,
I'm writing an UDF where I need to read and modify the value store in a rp real list created as follow:

(make-new-rpvar 'average_list '() 'real-list) 
(rpsetvar 'average_list ())
(rpsetvar 'average_list (list-add(rpgetvar 'average_list) 1.1))
(rpsetvar 'average_list (list-add(rpgetvar 'average_list) 2.2))
(rpsetvar 'average_list (list-add(rpgetvar 'average_list) 3.3))
(rpgetvar 'average_list )

I tried to use

RP_Get_List_Ref_Real("average_list",0)

and

RP_Set_List_Ref_Real("average_list",0)

, but doesn't work.
Can someone help me to solve this problem?
Thank you really much
Best regards
Denis

Hi Denis,

Please could you post the UDF code that does not work?

We know from the Fluent header file var.h that the function you mentioned should exist -- here it is (unless it has changed in recent versions):

FLUENT_EXPORT double RP_Get_List_Ref_Float(char *s, int n);

While we're in var.h, here are some useful functions:

FLUENT_EXPORT cxboolean RP_Variable_Exists_P(char *s);
FLUENT_EXPORT int RP_Get_List_Length(char *s);
FLUENT_EXPORT void RP_Set_List_of_Float(char *s, double *a, int length);

So I'm expecting something like:

#include "udf.h"
DEFINE_ON_DEMAND(read0)
{
  double value0;
  value0 = RP_Get_List_Ref_Float("average_list",0);
  Message0("value0 from average_list = %16.8g\n",value0);
}
DEFINE_ON_DEMAND(set4)
{
  double my_array[] = {0.,111.,222.,333.};
  int len_my_array;
  len_my_array = sizeof(my_array)/sizeof(my_array[0]);
  RP_Set_List_of_Float("average_list",my_array,len_my_array);
}

Sorry, I've written this without checking that it works.
Good luck!
Ed
