Dear all,
When I try to smooth the mesh with elliptic smoother, I cannot find any boundary type that allows the points to move in a line. The type is either fixed or floating, but what I want is only let the points float in the line? Any ideas? For example, say I have a two-block mesh, they are 1254 and 2365 1-2-3 | | | 4-5-6 Now, points 1,2,3 are in the same line. As I smooth the mesh, I hope point 2 can be freely moved, but it should always stay in the line, so are all the grid points on line 12 and line 23.

Daniel,
The orthogonal BC is what you want to use on edges that you want the points to slide along the connector without changing the connectors shape. Note, however, the ends of connectors, aka nodes, will not move. Only the internal points. If you really need point 2 to move, you will have to join the two domains then join the two connectors which share point 2. -Chris Quote:

I see, thank you! Then why not call it restricted-floating or on-boundary-floating or something. (I guess that even the "fixed" b.c. also will enforce an orthogonal grid on the b.c, right?)

The Angle Controls and Boundary Conditions accomplish two separate tasks. Setting the Boundary Condition to orthogonal allows the points to slide along the boundary to achieve orthogonality while the setting the Angle Control to orthogonal would bend the grid lines coming off the boundary to achieve orthogonality, a distance controlled by specifying the Blending and Decay Factor. |
