Hello everyone.
Is it possible to use a function handle within a femodel? So I could change the value of a material property or load, for example:
gm = multicuboid(0.5,0.1,0.1);
pdegplot(gm,FaceLabels="on",FaceAlpha=0.5);
% without function handles
model = femodel(AnalysisType="structuralStatic", ...
Geometry=gm);
E = 210e3;
P = 1000;
nu = 0.3;
model.MaterialProperties = materialProperties(YoungsModulus=E,PoissonsRatio=nu);
model.FaceLoad(2) = faceLoad(Pressure=P);
model.FaceBC(5) = faceBC("Constraint","fixed");
model = generateMesh(model);
r = solve(model);
pdeplot3D(r.Mesh,"Deformation",r.Displacement,"ColorMap",r.VonMisesStress);
% using function handles
model = femodel(AnalysisType="structuralStatic", ...
Geometry=gm);
E = @(x) x(1);
P = @(x) x(2);
model.MaterialProperties = materialProperties(YoungsModulus=E,PoissonsRatio=nu);
model.FaceLoad(2) = faceLoad(Pressure=P);
model.FaceBC(5) = faceBC("Constraint","fixed");
model = generateMesh(model);
values = [210e3 1000];
r = solve(model(values)); % I know it's wrong, once variable model has only one element, but I want to replace YoungsModulus property by values(1) and faceLoad(2) by values(2)
pdeplot3D(r.Mesh,"Deformation",r.Displacement,"ColorMap",r.VonMisesStress);

Hi Geovane,
You asked Is it possible to use a function handle within a femodel? So I could change the value of a material property or load.
My answer is yes, it is possible to employ function handles within a femodel in Matlab. By utilizing function handles, you can dynamically adjust material properties or loads during the simulation process. This flexibility allows for the creation of more versatile and adaptive femodels that can respond to changing conditions or requirements.
Hope that answers your question.
