Relative Expression

To specify a Relative Expression, set the Mesh size type to Relative Expression. This option allows you to specify a simple text expression to set the relative size of the mesh on all entities within the model.

You must enter the expression in the text entry area provided. The expression may be a function of x,y,z coordinates, and must follow the syntax described in the appendix. The following example illustrates an expression that enforces a mesh size of 0.5 at "y" locations greater than or equal to 0.0, and a mesh size of 0.1 at y locations having a value less than 0.0. value = if ( y >= 0, .5, .1). The mesh size that results from the expression is then multiplied by the length of the longest edge of the bounding box that completely encloses the entire model.
