Hi, I'm using MATLAB R2020a with PDE toolbox version 3.4 and my licenses are activated.
I wrote some short codes:
thePde = createpde();
model = importGeometry(thePde,'filename.stl');
pdegplot(model,'FaceLabels','on')
structuralProperties(model,'YoungsModulus',400e9,'PoissonsRatio',0.34);
structuralBC(model,'Face',36,'Constraint','fixed');
structuralBoundaryLoad(model,'Face',37,'SurfaceTraction',[0;0;-1e4]);
this is all(6 lines), I tried to
- import my 3D object CAD file "filename.stl" and graphically show it
- before doing finite element analysis, I tried to assign structural properties, boundary conditions.
The first one(importing&visuallizing) had no problem. But I have a trouble for second one, line 4~6 in codes:
Unrecognized function or variable 'structuralProperties'.
this is the error message I received after running. Also same errors for 'structuralBC' and 'structuralBoundaryLoad'. Now I am guessing that there is a problem in calling function, but I am not sure. What could be the problem?
Thanks for your advice.

Can you try 'rehash toolboxcache' in your command prompt and see if that works?
If this doesn't work then you can manually add the source code path(path where about functions are located) to your working directory.

Change the line:
thePde = createpde();
to
thePde = createpde('structural');
By default, createpde returns a model that has to deal with general equations-based interface. For structural analysis you need to specify the first argument as 'structural', this will create a structural analysis model for static analysis. If you want to do other types of structural analysis, then you need to pass a second argument that specifies analysis type. Check the options in createpde documentation page.

Ravi
