Model.loadcreatewithsystem

Model.loadcreatewithsystem(collection, config, type, comp1, comp2, comp3, comp4, comp5, comp6, system, transformflag)

Creates a load (force, moment, pressure, or constraint) at a node or element defined in a local coordinate system.

Parameters:

• collection (Collection) – The collection containing the entities.

• config (int) –

  The config of the load to create:

  1 - Force

  2 - Moment

  3 - Constraint

  5 - Temperature

  6 - Nodal Flux

  8 - Velocity

  9 - Acceleration

• type (int) – Solver dependent types of the referenced load config.

• comp1 (double) – The component of the load being applied. For all configs except constraints (config=3), this component represents the load in x-direction.

• comp2 (double) – The component of the load being applied. For all configs except constraints (config=3), this component represents the load in y-direction.

• comp3 (double) – The component of the load being applied. For all configs except constraints (config=3), this component represents the load in z-direction.

• comp4 (double) – The component of the load being applied. Applicable only for constraints (config=3).

• comp5 (double) – The component of the load being applied. Applicable only for constraints (config=3).

• comp6 (double) –

  The component of the load being applied. Applicable only for constraints (config=3).

  Note

  For constraints, all of the components are active unless they are set equal to -999999.0. All of the other components of the constraints are active in the respective directions.

  For pressures, to create a pressure which is normal to the element, set all components to zero.

• system (Entity) – The coordinate system to be used.

• transformflag (int) –

  Indicates which system supplies component values. Valid options are:

  0 - If the component values are supplied in the global coordinate system.

  1 - If the component values are supplied in the local coordinate system.

Examples

Apply a force of magnitude 10.0 along the x - axis of local system with ID 4 to nodes with IDs 5 and 25

import hm
import hm.entities as ent

model = hm.Model()

node_collection = hm.Collection(model, ent.Node, [5, 25])

model.loadcreatewithsystem(
    collection=node_collection,
    config=1,
    type=1,
    comp1=10.0,
    comp2=0.0,
    comp3=0.0,
    comp4=0.0,
    comp5=0.0,
    comp6=0.0,
    system=ent.System(model, 4),
    transformflag=1,
)

Apply a constraint of zero in the global translational x - axis (comp1 ) , in the translational z - axis (comp3 ) , in the rotational y - axis (comp5 ) to nodes with ID 12 , 13 , and 14 , but have the constraint communicated to the solver in the local coordinate system with ID 4

import hm
import hm.entities as ent

model = hm.Model()

node_collection = hm.Collection(model, ent.Node, [12, 13, 14])

model.loadcreatewithsystem(
    collection=node_collection,
    config=3,
    type=1,
    comp1=0.0,
    comp2=999999.0,
    comp3=0.0,
    comp4=999999.0,
    comp5=0.0,
    comp6=999999.0,
    system=ent.System(model, 4),
    transformflag=0,
)
