findBodyLoad

Find body load assigned to geometric region

Syntax

bl = findBodyLoad(structuralmodel.BodyLoads,RegionType,RegionID)

Description

bl = findBodyLoad(structuralmodel.BodyLoads,RegionType,RegionID) returns the body load assigned to a geometric region of the structural model. A body load must use units consistent with the geometry and other model attributes.

Examples

Find Body Load

Create a structural model.

structuralModel = createpde('structural','static-solid');

Create and plot the geometry.

gm = multicuboid(0.5,0.1,0.1);
structuralModel.Geometry = gm;
pdegplot(structuralModel,'FaceAlpha',0.5)

Specify the Young's modulus, Poisson's ratio, and mass density. Notice that the mass density value is required for modeling gravitational effects.

structuralProperties(structuralModel,'YoungsModulus',210E3, ...
                                     'PoissonsRatio',0.3,...
                                     'MassDensity',2.7E-6);

Specify the gravity load on the beam.

structuralBodyLoad(structuralModel,'GravitationalAcceleration',[0;0;-9.8]);

Check the body load specification for cell 1.

findBodyLoad(structuralModel.BodyLoads,'Cell',1)

ans = 
  BodyLoadAssignment with properties:

                   RegionType: 'Cell'
                     RegionID: 1
    GravitationalAcceleration: [3x1 double]
                  Temperature: []

Input Arguments

structuralmodel.BodyLoads — Body loads

BodyLoads property of StructuralModel object

Body loads of the model, specified as a BodyLoads property of a StructuralModel object.

RegionType — Geometric region type

'Face' for a 2-D model | 'Cell' for a 3-D model

Geometric region type, specified as 'Face' for a 2-D model or 'Cell' for a 3-D model.

Example: findBodyLoad(structuralmodel.BodyLoads,'Cell',1)

Data Types: char | string

RegionID — Geometric region ID

vector of positive integers

Geometric region ID, specified as a vector of positive integers. Find the region IDs using pdegplot, as shown in Create Geometry and Remove Face Boundaries or STL File Import.

Example: findBodyLoad(structuralmodel.BodyLoads,'Cell',1)

Data Types: double

Output Arguments

bl — Body load assignment

BodyLoadAssignment object

Body load assignment, returned as a BodyLoadAssignment object. For details, see BodyLoadAssignment Properties.
