Model.penetrationchecktwo

Model.penetrationchecktwo(collection1, collection2, segment_orientation, partscale_contthick_toggle, part_scale, cont_thick)

Checks penetration for entities selection type groups, elems2elems, nodes2elems, and elemsonly. To release the memory after completion, use the function penetrationcheckend(). A valid template must be loaded for the check to occur.

Parameters:

• collection1 (Collection) – The collection containing the first entities to check for penetration.

• collection2 (Collection) – The collection containing the second entities to check for penetration.

• segment_orientation (int) –

  Flag for taking element normal into consideration for checking penetration.

  0 - Elements normal will not be considered

  1 - Elements normal will be considered

• partscale_contthick_toggle (int) –

  1 - If part thickness scale is selected

  2 - If contact thickness is selected

• part_scale (double) – Value of part scale factor.

• cont_thick (double) – Value of contact thickness.

Examples

Check penetration between elems2elems with segment orientation option and part thickness scale

import hm
import hm.entities as ent

model = hm.Model()

# Creating collection of elements from components for checking penetration
col1 = hm.Collection(
    model, ent.Element, hm.Collection(model, ent.Component, "name=plate")
)
col2 = hm.Collection(
    model, ent.Element, hm.Collection(model, ent.Component, "name=esfera")
)

model.penetrationchecktwo(
    collection1=col1,
    collection2=col2,
    segment_orientation=1,
    partscale_contthick_toggle=1,
    part_scale=1.0,
    cont_thick=0.0,
)

Check penetration between nodes2elems without segment orientation option and with contact thickness

import hm
import hm.entities as ent

model = hm.Model()

# Creating collection of elements & nodes from components for checking penetration
col1 = hm.Collection(
    model, ent.Element, hm.Collection(model, ent.Component, "name=plate")
)
col2 = hm.Collection(
    model, ent.Node, hm.Collection(model, ent.Component, "name=esfera")
)

model.penetrationchecktwo(
    collection1=col1,
    collection2=col2,
    segment_orientation=1,
    partscale_contthick_toggle=1,
    part_scale=1.0,
    cont_thick=0.0,
)
