I have the attached UDF that has worked for another user but isn't working for me. I'm running Fluent on a UNIX system. When I try to interpret this UDF, I keep getting a syntax error that is said to be in Line 2. I can't seem to figure it out. Can someone help?

#include "udf.h"
DEFINE_PROFILE(inflow_v, t, nv)
{
face_t f ;
real flow_time = RP_Get_Real("flow-time");
real A = 16.999874;
real v1 = 0.0;
real v2 = 1034*(0.3048*0.3048*0.3048)/A;

if (flow_time <= 7 )
{
begin_f_loop(f,t)
{
F_PROFILE(f,t,nv) = -1*(v1+(v2-v1)*(flow_time-0)/7);
}
end_f_loop(f,t)

printf("Time = %f sec. \n",flow_time);
printf("Flow rate set at %f cfs \n", -1*(v1+(v2-v1)*(flow_time-0)/7)*A/(0.3048*0.3048*0.3048));
}
else
{
begin_f_loop(f,t)
{
F_PROFILE(f,t,nv) = -1.722343325;
}
end_f_loop(f,t)

printf("Time = %f sec. \n",flow_time);
printf("Flow rate set at %f cfs \n", -1.722343325*A/(0.3048*0.3048*0.3048));
}
}

I can interpret this without any issue. Probably ur Fluent installation is fucked, I'd try to re-install the entire thing, otherwise I don't know, sorry and good luck to you.

Before going as far as reinstalling the software, you could try to compiling the code instead of interpreting it. Second thing worth trying is to double check that the file in which the code is saved is in correct form. With this I mean that the file has been somehow altered for instance if it has been read and written in a windows environment and then handled in an unix environment. You could create a new file in your unix environment and copy-paste the code in the new file. Hope this helps, albeit it might seem a long shot!
