Hello People,

I wanna build some custom boundary velocity profile for my Fluent case running in parallel with 2 nodes.

I wrote this c source code:

#include "udf.h"
#include "math.h"
#include "stdio.h"

#define z0 1e-2 //unit m
#define zref 6 //unit m
#define k 0.4 //cte Von Karman
#define vref 35.7632 //unit m/s

DEFINE_PROFILE(xvinlet,t,i)
{
    float X[ND_ND];
    float u,h,Vwind,Vtrain;
    int alfa;
    face_t f;
    FILE *fp;
    
    fp=fopen("inputs.txt","r");
    fscanf(fp,"%i %f",&alfa,&Vtrain);
    fclose(fp);

    u=(k*vref)/(log((zref+z0)/z0));

#if !RP_HOST /* serial or node */    
        
    begin_f_loop(f,t)
    {
        F_CENTROID(X,f,t);
        h=X[1];
        Vwind=(u/k)*log((h+z0)/z0);
        F_PROFILE(f,t,i)=-Vwind*cos(alfa)-Vtrain;
    }
    end_f_loop(f,t);
#endif
}

When i tried to compile it, Fluent brought me this log:

Done.

As everybody can see, the compiler make a new source file called udf_names.c that have a fail in 8th lane (C4113). I dont know how to solve it. Please help me.

My system is:

• win7x64 profesional
• Fluent 15.07
• MSVC 2012 Express
• .Net Framework 4.5
• Microsoft SDK 7.1

I opened Fluent with the SDK command prompt, so enviromment variables should be fine.

The udf_names.c source code that automatically created the compiler is:

/* This file generated automatically. */ 
/* Do not modify. */ 
#include "udf.h" 
#include "prop.h" 
#include "dpm.h" 
extern DEFINE_PROFILE(xvinlet,t,i);
__declspec(dllexport) UDF_Data udf_data[] = { 
{"xvinlet", (void (*)())xvinlet, UDF_TYPE_PROFILE},
}; 
__declspec(dllexport) int n_udf_data = sizeof(udf_data)/sizeof(UDF_Data); 
#include "version.h" 
__declspec(dllexport) void UDF_Inquire_Release(int *major, int *minor, int *revision) 
{ 
*major = RampantReleaseMajor; 
*minor = RampantReleaseMinor; 
*revision = RampantReleaseRevision; 
}

<edited> I solved LNK200 and LNK1120 moving the #if RP_HOST condition inside the DEFINE_PROFILE macro as we can see now, but the c4113 error still persist. The libudf.dll can be loaded but i dont know if its will work fine.

In my experience, that error C4113 can be safely ignored, it is a mistake by the Fluent programmers that does not have any real consequences.

I would be more concerned with the two other errors that are shown: LNK2001 and LNK1120. Those are new for me.
