Model.hm_wadlinessetentities_bymode#

Model.hm_wadlinessetentities_bymode(collection_front, mode)#

Sets the entities used for a WAD lines analysis.

Parameters:

  • collection_front (Collection) – The collection containing the front entities of the vehicle.

  • mode (hwString) – The string all_in_one to denote all entities are given in collection_front, or front_only to run only a front bumper analysis.

Returns:

Setup and extract WAD lines data by put all entities on the first collection#

The example can be modified instead to only run a bumper analysis#
# ...

comps = hm.Collection(
    model, ent.Component, "Name=bonnet OR Name=bumper OR Name=fenderL OR Name=fenderR"
)

model.hm_wadlinessetentities_bymode(collection_front=comps, mode="front_only")
