In Ansys Workbench , Fluent, CFX, Static-structural & thermal, Transient -structural & thermal, etc are available. Which is better to use and how ?
You should be use Heat flux input for moving heat source. Firstly you find heat flux by the help of moving componen
#include "udf.h"
DEFINE_PROFILE(Qfield, thread, position)
{
real coord[ND_ND];
real x,y,z; // coordinates
real xC=0.0075,yC=0.0075,zC=0.005; // initial position of heater
real D = 7e-5; // the heater diameter (m)
real V = 0.05; // the heater moving velocity (m/s)
real P = 5.0; // (W)
real i = 1;
real h = D*1;
real t; // time
real t0 = 1e-3; // the time that the heater is stationary
face_t f; // system parameter
//real RigionX = D*10;
real RigionX = 0.0075; // region (heating face) size (m)
real R,Rk,q0,r2;
R = D/2;
q0 = (2*P)/(3.14159268*(R*R));
t = RP_Get_Real("flow-time"); //
// heater path
if(t < t0)
{
xC = xC;
//yC = yC+(i*h);
//zC = zC;
yC = yC;
zC = zC;
}
else
{
t = t-t0;
while( (t*V) > 0.0075 )
{
t = t - (0.0075/V);
}
xC = xC+V*t;
yC = yC+V*t;
zC = zC;
}
//yC = yC+(i*h);
//xC = xC+(i*h);
//while( (t*V) > RigionX )
//while( (t*V) > RigionX )
// t = t - RigionX/V;
//i=i+1;
// Specifying the shape and position of the heater spot at a certain point in time
// iteration over the heating side
begin_f_loop(f,thread)
{
F_CENTROID(coord,f,thread);
x = coord[0];
y = coord[2];
z = coord[2];
r2 = sqrt(((x-xC)*(x-xC))+((y-yC)*(y-yC)));
F_PROFILE(f,thread,position) = 0.3*(((2*P)/(3.14159268*(R*R)))*exp((-2*(r2*r2))/(R*R)));
// F_PROFILE(f,thread,position) =(2*P/((3.1415926)*(R*R)))*exp(-2*(((r2*r2))/((R*R)))))
}
end_f_loop(f,thread)
}
Should I insert that code as a command block? and if so where would I put it?
