hi all,
please i have a problem in my udf ;
#include "udf.h"
DEFINE_PROPERTY(conc,c,t)
{
real R = C_R(c,t);
real YI = C_YI(c,t,1)
C_UDMI(c,t,0) = YI*(R*1000);
return
}
is interpreted sucessfully, but after running for1 one iteration it is giving Access_violation error. but juste when i add the YI without YI the udf runing normaly.

thank
best regards

Rubis,

You're not returning any values from the function. The define property macro specifies a material/fluid property, and expects a return value.
