Find body load assigned to geometric region


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



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.

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;

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, ...

Specify the gravity load on the beam.


Check the body load specification for cell 1.

ans = 
  BodyLoadAssignment with properties:

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

Input Arguments

collapse all

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

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

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

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