My UDF got interpreted and hooked. But when I try to initialize it gives error message: Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()

I dont know what does this ACCESS_VIOLATION error means.Help me out with this

do not forget to give the number of your UDMI or UDSI in the fluent interface

hey i couldnt get properly what you are saying. my UDF is this: DEFINE_PROFILE(contact_angle,thread,i) {

float vel;//[10];

float Ca ;

float THETA_D;

float time;

face_t f;

for (time = 0 ; time <= 10 ; time = time + 0.00001)

{

if (time == CURRENT_TIME)

{

begin_f_loop(f, thread)

{

if (F_VOF(f, thread)==0.5)

{

vel=F_U(f, thread);

Ca=(vel*VISCOSITY)/SUR_TEN;

F_PROFILE(f,thread,i)=pow((pow(THETA_E,3)+9*Ca*log (LAMDA)), 0.3333);

}

else F_PROFILE(f,thread,i)=120;

}

end_f_loop(f, thread)

}

} }

please have a look at this and let me know what i need to do

in the graphic interface you but

/solve/set/expert

and for question about Keep temporary solver memory from being freed, you must but yes

what have u written? sorry but its not making any sense

sorry,in the graphic Fluent interface you write

/solve/set/expert

+ entry

and for question about Keep temporary solver memory from being freed, you must but yes

Are you running this code in windows interface or Unix/linux. If you write the code in dos and run in linux then you should face some problem. you have to convert like dos2unix or something like this........

regards Suvash

i got rid of this problem...thanx for your help
