Relax moves the bowl away from its original contours
The Relax modifier changes the apparent surface tension in a mesh by moving vertices closer to, or away from, their neighbors. The typical result is that the object gets smoother and a little smaller as the vertices move towards an averaged center point. You can see the most pronounced effects on objects with sharp corners and edges.
When you apply Relax, each vertex is compared to the position of its neighboring vertices and moved toward or away from the average position of its neighbors. A neighboring vertex is one that shares a visible edge with the current vertex.
A patch object input to the Relax modifier retains its patch definition. Files that contain patch objects with the Relax modifier from previous versions of the software will be converted to meshes to maintain backward compatibility.
Original objects compared to relaxed objects
The Relax Value parameter controls how far a vertex moves for each iteration. The value specifies a percentage of the distance from the original location of a vertex to the average location of its neighbors:
Positive Relax Values: Moves each vertex in closer to its neighbors. The object becomes smoother and smaller.
Relax Value of 0.0: Vertices do not move and Relax has no affect on the object.
Negative Relax Values: Moves each vertex away from its neighbors. The object becomes more irregular and larger.
Relax Values=1.0, 0.0, -1.0
Iterations=1 (default)
The Iterations parameter sets how many times to repeat the Relax process. For each iteration, average locations are recalculated and the Relax Value is reapplied to every vertex.
For 0 iterations, no relax is applied.
Increasing iterations for positive relax values smoothes and shrinks an object. With very large iteration values, the object shrinks to a point.
Increasing iterations for negative relax values exaggerates and expands an object. With relatively few iterations. the object becomes jumbled and almost unusable.
Iterations=0, 10, 50
Relax Value=0.5 (default)
Iterations=0,1, 5
Relax Value=-0.5
The Keep Boundary Pts Fixed check box controls whether vertices at the edges of open meshes are moved.
When on: Boundary vertices do not move while the rest of the object is relaxed. This option is particularly useful when working with multiple objects, or multiple elements within a single object, that share open edges.
When off: Relaxes all vertices of the object.
Keep Boundary Pts Fixed=on

Interface
Relax Value: Sets the distance a vertex moves as a percentage of the distance between a vertex and the average location of its neighbors. Range=-1.0 to 1.0. Default=0.5.
Iterations: Sets how many times Relax is repeated. Each iteration recalculates average vertex locations based on the result of the previous iteration. Default=1.
Keep Boundary Pts Fixed: Vertices at the edge of open meshes do not relax. Default=on.
Save Outer Corners: Preserves the original positions of vertices farthest away from the object center.
