*setedgedensitylinkwithaspectratio

Syntax

*setedgedensitylinkwithaspectratio aspectratio

Type

HyperMesh Tcl Modify

Description

This command sets the method for linking opposite edge densities during automeshing. This forces opposite edges of a surface to use consistent edge densities, provided that the starting densities are close enough. This creates tapered lines of elements, instead of using trias to transition between inconsistent densities. This is only valid for size and bias or edge deviation surface meshing.

Inputs

aspectratio

Specifies the aspect ratio to use for edge density linking. Valid values are:

• -1 - Do not link opposite edge densities.
• 0 - Attempt to link opposite edge densities with default value.
• > 0 - Attempt to link opposite edge densities with specified value.

Example

To mesh surface 12 with first order elements of size 0.5, and specifying an edge density link using a value of 2:

*setedgedensitylinkwithaspectratio 2
*setoption element_order=1
*createmark surfaces 1 12
*interactiveremeshsurf 1 1 2 2 2 1 1
*set_meshfaceparams 0 2 2 0 0 1 0.5 1 1 
*set_meshedgeparams 0 32 1 0 0 0 1 0 0
*set_meshedgeparams 3 5 1 0 0 0 1 0 0
*automesh 0 2 2
*storemeshtodatabase 1
*ameshclearsurface

Errors

None.
