PREVIOUS_2_TIME Macro giving error while interpret.

nvarma · September 25, 2019, 10:08

the UDF manual doesn't say any limitations on this macro other than to include the unsteady.h header which I have. PREVIOUS_TIME also seem to work. However, PREVIOUS_2_TIME doesn't seem to work and gives the following error:

"label "dt_factor" not found "

Note that my udf does not have anything called dt_factor. Also the udf works as soon as I comment out the "t2=PREVIOUS_2_TIME;" line.

thanks for any help or guesses.

Code:

#include "udf.h"
#include "unsteady.h"

real time2;
DEFINE_ON_DEMAND(name_any)
{
time2=PREVIOUS_2_TIME;
}

is compiled with no errors

best regards
