Syntax

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

Description

example

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.

Open Live Script

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)

Figure contains an axes object. The axes object contains 3 objects of type quiver, patch, line.

Specify Young's modulus, Poisson's ratio, and the 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]

Input Arguments

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 by using pdegplot.

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

Data Types: double
