Model.setedgedensitylinkbytypeandaspectratio

Model.setedgedensitylinkbytypeandaspectratio(type, aspect_ratio)

Sets the method and aspect ratio 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.

Parameters:

• type (int) –

  0 - No edge linking, aspect ratio is ignored.

  1 - Aspect ratio is valid. Equivalent to Model.setedgedensitylinkwithaspectratio().

  2 - Forced edge linking, aspect ratio is ignored.

• aspect_ratio (double) –

  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.

Examples

Mesh surfaces specifying an edge density link using a value of 3.0

import hm
import hm.entities as ent

model = hm.Model()

model.setedgedensitylinkbytypeandaspectratio(type=1, aspect_ratio=3.0)

Disable link

import hm
import hm.entities as ent

model = hm.Model()

model.setedgedensitylinkbytypeandaspectratio(type=0, aspect_ratio=0)

Force edge link , if possible

import hm
import hm.entities as ent

model = hm.Model()

model.setedgedensitylinkbytypeandaspectratio(type=2, aspect_ratio=0)
