Model.createsolidsfromshells(input_collection, output_collection, comp_create_option=0, solid_layers=0, fill_gaps=0, delete_shells=0, property_create=0, reserved1=0, reserved2=0, reserved3=0)

Creates solid elements from shell elements. This API currently works only on composite ply-based models for OptiStruct/Nastran and Abaqus. Zone-based models are not supported, nor are metallic models.

Parameters:

• input_collection (Collection) – The collection that holds the shell elements. Valid entities are plies and laminates.

• output_collection (Collection) – The collection containing the newly created solid elements.

• comp_create_option (int) –

  Organization method for newly created solid elements:

  0 - Current component.

  1 - Create a new component for each ply (valid only if entity_type is set to plies and solid_layers is set to 0).

  2 - Create a new component for all solid elements created.

• solid_layers (int) –

  Valid if entity_type is set to plies only:

  0 - Create solids for each layer.

  1 - Create single solids for all layers.

• fill_gaps (int) –

  0 - Gaps between layers will not be filled.

  1 - Gaps between layers filled with solids.

• delete_shells (int) –

  0 - Keep input shell elements.

  1 - Delete input shell elements.

• property_create (int) –

  0 - No properties created/assigned for created solids.

  1 - An appropriate property will be created and assigned to the solid elements.

• reserved1 (unsigned int) – Reserved for future use. Must be set to 0.

• reserved2 (double) – Reserved for future use. Must be set to 0.

• reserved3 (double) – Reserved for future use. Must be set to 0.

Example

Convert all shell elements in a ply named “ Ply3 “ to solids , create solids for each layer , without fill the gaps between layers . A new component and appropriate property should be created and assigned to the solids , delete the exist shells

import hm
import hm.entities as ent

model = hm.Model()

plies = hm.Collection(model, ent.Ply, "name=Ply3")
solids = hm.Collection(model, ent.Element, populate=False)
