Hi everyone,


I am trying to upload a User Defined Function to Ansys and it gives me the following error:

line 18: invalid type for binary expression: int + pointer to structure.


Here is the code that I am trying use:

#include"udf.h"
DEFINE_PROPERTY(moving_wall, thread, u)
{

/* Declare variables */
float t, speed;
face_t f;

/* Get time */
t = RP_Get_Real("flow-time");

/* Calculate speed */
speed = 1.6 * sin(3.8 * t);

/* Apply speed to face */
begin_f_loop(f, thread)
{
F_PROFILE(f, thread, u) = speed;
}
end_f_loop(f, thread)
}



*PS - I am new to Ansys and coding so please dont use any shorthand explanations, if possible.

Thank you!

Hi, i can try to help you. what is line 18? there is not numbering.

anyway it seems you are combining differt type of variable, can you debug and identify the wrong command line? 

 

Thanks

Hi Luca,

 

Thank you for the response.

 

I tried to copy and paste the code from a PDF, originally. And it didnt want to work. I eventually typed out the code over from scratch, and then it worked fine!
