I'm pretty sure that I have no problem with the ; and ')', but still I got that error. Some said it is because of the compiler, but I followed the ansys technical support's direction, using vs 2010 express edition+windows sdk 7.0+.net framework 3.5 sp1 to start fluent in my win7 64bit system.

Fluent can be smoothly started without problem.


Please help.


Thanks.

I don't know if that was your case, but there is a C rule that can be very annoying for one that is not aware of it. You should put every declaration before any operation. As an example, this produces the kind of error you got:

Code:
 
 int j;
 j = 1;
 int i;

If you have the same error then post your UDF code. The error code states the line number where the error has occurred.

Thanks for the reply.. code is below


#include "udf.h"
#define a 340.26

DEFINE_ON_DEMAND(shock_sensor)
{
Domain *d;
Thread *t;
cell_t c;
d=Get_Domain(1);

real f_shock, velocity;
thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
velocity=(C_U(c,t)+C_V(c,t));
f_shock = (velocity*C_P_G(c,t))/(a*abs(C_P_G(c,t)));

if(f_shock>=1)
{
C_UDMI(c,t,0)=f_shock;
}
}
end_c_loop(c,t)
}
}

I think I need to change the macro, but not sure...

Thanks

Are you running in serial or parallel, and what is your error message exactly?

First of all, you should declare your variables before assigning values to them as pointed out by Micael in this thread we're currently in.

Try:

Code:
Domain *d;
Thread *t;
cell_t c;
real f_shock, velocity;
d=Get_Domain(1);

Thank you. Awesome suggestion, my errors reduced but still got 3 errors. I think I need to change the macro, not sure. I'm running on serial right now and will attach my sensor and viscous algorithm.

UDF is this

#include "udf.h"
#define A 340.26

DEFINE_ON_DEMAND(shock_sensor)
{
Domain *d;
Thread *t;
cell_t c;
real f_shock, velocity;
d=Get_Domain(1);


thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
velocity=(C_U(c,t)+C_V(c,t));
f_shock = (velocity*C_P_G(c,t))/(A*fabs(C_P_G(c,t)));

if(f_shock>=1)
{
C_UDMI(c,t,0)=f_shock;
}
}
end_c_loop(c,t)
}
}



Error is below.


# Generating ud_io1.h
shock_sensor.c
..\..\src\shock_sensor.c(18) : error C2297: '*' : illegal, right operand has type 'real [2]'
..\..\src\shock_sensor.c(18) : error C2440: 'function' : cannot convert from 'real [2]' to 'double'
..\..\src\shock_sensor.c(18) : warning C4024: 'fabs' : different types for formal and actual parameter 1

Done.


Thanks in advance
