How to write udf code in visual studio
 

I change the program for 3d.
But it's show the error msg that is udf library trying to load is not compiled for current platform.
I used visual Studio 2017 for as compiler. And some time it's give error fatal error C1189.
This is code. Please tell me how to avoid this error..


#include "udf.h"
DEFINE_GRID_MOTION(logarithmic, domain, dt, time, dtime)
{ Thread *tf=DT_THREAD(dt);
face_t f;
Node *v;
real NV_VEC(velocity),NV_VEC(axis);
real NV_VEC(origin),NV_VEC(rvec);
real loco;
real freq;
real amp;
real diam;
int n;
SET_DEFORMING_THREAD_FLAG(THREAD_T0(tf));
freq=200;
amp=0.00152;
diam=0.050;
loco=2*3.141592654*amp*freq*cos(2*3.141592654*freq *time);
Message("time=%f,omeg=%f\n",time,loco);
NV_S(velocity,=,0.0);
NV_D(axis,=,1.0,1.0,1.0);
NV_D(origin,=,0.0,0.0,0.0);
begin_f_loop(f, tf)
{ f_node_loop(f, tf, n)
{ v=F_NODE (f, tf, n);
if (NODE_POS_NEED_UPDATE(v))
{ NODE_POS_UPDATED(v);
velocity[2]=loco*(1-(4*(sqrt((NODE_X(v)*NODE_X(v))+(NODE_Y(v)*NODE_Y(v ))))*(sqrt((NODE_X(v)*NODE_X(v))+(NODE_Y(v)*NODE_Y (v)))))/(diam*diam)+((8*(sqrt((NODE_X(v)*NODE_X(v))+(NODE_ Y(v)*NODE_Y(v))))*(sqrt((NODE_X(v)*NODE_X(v))+(NOD E_Y(v)*NODE_Y(v)))))/(diam*diam))*(log((2*(sqrt((NODE_X(v)*NODE_X(v))+( NODE_Y(v)*NODE_Y(v))))+0.000000000001)/diam)));
NV_V_VS(rvec,=,NODE_COORD(v),+,velocity,*,dtime);
NV_V(NODE_COORD(v),=,rvec); } } }
end_f_loop (f, tf); }

This code is for 2d analysis of synthetic jet

I am using this code for 2d analysis in visual studio but it is showing many errors like-
1] cannot find the open source files.
2] identifier logarithmic undefined; identifier domain undefined; identifier dt undefined etc
3]expected an expression
and there are some more ... can help me solve this issue as I am not good at coding.

I just code it in fluent,it works successfully，no errors.
you'd better make some settings between the fluent and VS++.
The VS++ must include the header file like the "udf.h"or others.
please try it again,good luck!
