Hi
when we run fluent in double precision mode,how we can return a normal number to solver in double precision mode in udfs?when I return a normal number in udf in double precision mode fllowing error in reported :

original udf :

#include "udf.h"
#include "dpm.h"

DEFINE_DPM_TIMESTEP(payam,p,dt)
{
return 0.01;
}

Error:
"function returning double returns float"

Maybe this works:

#include "udf.h"
#include "dpm.h"

DEFINE_DPM_TIMESTEP(payam,p,dt)
{
real X = 0.01;
return X;
}
