Hi everyone
I have written a UDF for sinusoidal wave propagation at a channel wall. the wall should deform according to the equation in order to initialize the flow inside the channel.
#include "udf.h"
#include<stdlib.h>
#include<math.h>

#define AH 0.1 // Average Height of Channel
#define XL 1.0 // Length
#define WA 0.01 // Wave Amplitude
#define PI 3.1415925
#define C 0.05 //Wave Speed
#define Lambda 3.0 // wavelength

#define XStep 0.001
#define XSize XL/XStep

#define HStep 0.0001
#define HSize AH/HStep

DEFINE_GRID_MOTION(peristaltic, domain, dt, time, dtime)
{
Thread *tf= DT_THREAD(dt);
face_t f;

float curr_time = CURRENT_TIME;

float xVec[XSize];
xVec[0] = 0;
for (int counter = 1; counter < XSize; counter++)
xVec[counter] = xVec[counter - 1] + XStep;

float hVec[HSize];

i=1;
begin_f_loop(f,tf)
{
curr_time = CURRENT_TIME;
float sint = sin (2 * PI/Lambda * xVec[i] - C * curr_time);
hVec[i] = AH * WA * sint;
i = i + 1;
}
}
kindly I need comments. Is this right according to my case problem details are attached.

I am not yet able to run this code as I am having troubles in loading this UDF as compiled. I have installed Microsoft visual studio express 2010 and SDK 7.0. I am using ANSYS fluent 14.5. yet it gives an error as shown in the attachment.

I have got this problem too
And I have solved ít by using VS Ultimate version.
So try it now

Thank you. I am going to install VS ultimate. Do I have to change the path in system variables after the installation?

[Havinh]

in my experiment, it's not necessary. I just install ultimate version and everything run perfectly

I have installed microsoft VS 2010 ultimate but still getting this error"xcopy is not recognized as an internal or external command, operable program or batch file" when i try to build the library. it builds the library "libudf" along with showing the above error. after that when i click load it gives the same old error message" the library u r trying to load (libudf) is not compiledfor 2d on the current platform (win64), the system cannot find the file specified .... D:\... libudf.dll"
I really don't know what else I can do to get this code compiled!

At last my Fluent is able to compile UDF's. I shifted to 32 bit versions and it did the job for me. Just installed MS visual studio 2010 professional and ran fluent from MS visual studio cross tool command prompt.
After running my UDF it gives the following errors.

Done.
Can any body guide me in this regard
