Hi,

I would like to give heat flux from a surface depending on timestep. So I wrote an UDF for serial (haven't tried yet if it is working btw), but I am not sure if I need to paralellize it when I use parallel solver.

I would like to use DEFINE_PROFILE as follows:


---------------------------------------------------------
#include "udf.h"

DEFINE_PROFILE(hf_profile,t,i)
{
real x[ND_ND];
real y;
face_t f;

if (CURRENT_TIME > 5 && CURRENT_TIME < 8) {
F_PROFILE(f,t,i) = 100;
}
else if (CURRENT_TIME >= 8 && CURRENT_TIME < 15) {

F_PROFILE(f,t,i) = 150;
}
}


How should I need to add #if !RP_HOST or !RP_NODE ? I did not quite understand from the manual if I need to use these parallel functions because I think I am not using global functions.

Thank you in advance,

#include "udf.h"

DEFINE_PROFILE(hf_profile,t,i)
{
face_t f;
begin_f_loop(f,t)
{
if (CURRENT_TIME > 5 && CURRENT_TIME < 8) 
	{F_PROFILE(f,t,i) = 100;}
	else if (CURRENT_TIME >= 8 && CURRENT_TIME < 15) 
	{F_PROFILE(f,t,i) = 150;}
}
end_f_loop(f,t)
}

you don't use x and y variables in your code, so I removed them
you don't need to modify your code to use it in parallel

best regards

Thank you AlexanderZ,

But Do I need to write a loop? I would like to give heatflux from one surface only.
