Hello,
I created a codedFixedBC with the following code vector dir1 = vector(1,0,0); vector dir2 = vector(0,1,0); scalarField x = patch().Cf()&dir1; scalarField y = patch().Cf()&dir2; scalarField r = pow(pow(x,2) + pow(y,2),0.5); operator == (vector(0,0,1)*r); If it isn't evident the boundary condition is supposed to be linear growth in U_3 over a circular domain as a function of r If I run the code for a single time step I can look at the nonuniform list<vector> for the patch at which this BC is applied. Here I can see a point having the value (0,0,0) which I would expect at the origin. If I examine the data in paraView using data along a line, or a point probe there is a non zero value of U_3 at (0,0,0). In fact the linear profile shows a distinct non zero plateau as the origin is approached. Am I doing something dumb in paraView or is there actually a problem with my BC? Any input is appreciated. -Jensen |
