1 how to set the Neumann boundary condition in COMSOL 4.3b?
We just find the Dirichlet boundary condition setting Options
2 Unable to assign line charge density for the line segment
We treat the line segment as the source term, and however , when setting the source, the line segment cannot be selected.
And the, I add two rectangle with very small width to replace the line segment, the line charge density can be set.
3 after solve the project, we should deal the data in Matlab.
3.1 how to get the value (Potential distribution)along the line segment?
As the mesh grid in not uniform, so how to get the Coordinate along the line segment?
3.2 Take segment2 endpoint as the center, how to get the gradient of each point on the circumference to the center?
Is there any nesecery to determine the coordinates of each point on the circumference?
