Model.cleanupmodelfile

Model.cleanupmodelfile(collection_set, x0, y0, z0, x1, y1, z1, operation)

Cleans up model specific data after a box trim operation.

Parameters:

• collection_set (CollectionSet) – The set of collections containing possibly multiple type of input entities. The use depends on the operation argument. Valid entities are Groups, Controlvols and Loads.

• x0 (double) – Lower bound x-coordinate.

• y0 (double) – Lower bound y-coordinate.

• z0 (double) – Lower bound z-coordinate.

• x1 (double) – Upper bound x-coordinate.

• y1 (double) – Upper bound y-coordinate.

• z1 (double) – Upper bound z-coordinate.

• operation (hwString) –

  The operation to perform. Valid values are:

  deleteoutsidebox - Deletes all elements, connectors, blocks and groups outside the specified box.

  deleteemptyunused - Deletes all empty components, assemblies, sets, contactsurfs, outputblocks, groups, plies and rigidwalls, and all unused materials, properties, sets, beamsects, curves, systems, vectors, laminates, plies and tables. collection_set and x0 through z1 are ignored.

  preservesolverdata - Preserves all control cards by adding them to collection_set. x0 through z1 are ignored.

  postclean - Delete the rest of the items not on collection_set. x0 through z1 are ignored.

Example

Cleanup model and solver data for LS-DYNA, using a box of 0, 0, 0 - 100,100,100

import hm.entities as ent

model = hm.Model()

template_type = "lsdyna"

)
element_collection = hm.Collection(model, filter)

colset = hm.CollectionSet(model)
colset.set(element_collection)
