# Relax Graph

Perform a relaxation on the graph. This block will move the vertices with the objective of creating uniform beam lengths.

### Inputs

| Name | Type | Description |
| - | - | - |
| Graph | [Graph](../../../../block-documentation/types/graph) | The Graph to relax. |
| Surface | [Implicit Body](../../../../block-documentation/types/implicit-body) | The surface which to constrain the graph vertices. Vertices starting within the domain Tolerance will be constrained to the surface of this body. |
| Max iterations | [Integer](../../../../block-documentation/types/integer) | The maximum number of iterations during the relaxation process. |
| Min angle | [Scalar](../../../../block-documentation/types/scalar) | The minimum angle between beams. The relaxation process will attempt to prevent any beam angles below this threshold. The input value should be between 0 and 180.0 degrees. |
| Volume | [Implicit Body](../../../../block-documentation/types/implicit-body) | A secondary domain in the volume of which to constrain the graph vertices. This is typically a loop around the trimmed ends of the graph. Vertices will be able to move within this domain, but not away from it. |
| Tolerance | [Scalar](../../../../block-documentation/types/scalar) | The maximum deviation outside the Domain. If no value is provided, the block will calculate a tolerance based on the graph. The input value should be always positive. |
| Move limit | [Scalar](../../../../block-documentation/types/scalar) | The maximum amount of movement per graph vertex between iterations. A smaller value may increase stability at the cost of a reduced convergence rate. If left unspecified, the block will calculate a move limit based on the graph. |
| Passive region | [Implicit Body](../../../../block-documentation/types/implicit-body) | Region in which all vertices are unmodified. All vertices within this region will have a displacement of zero. |
