Why do I receive the error: Unrecognized function or variable 'applyBoun​daryCondit​ion'.

Hello everybody,

I am trying to simulate an electrosdtatic field in a chamber coposed of several elements. I have defined the geometry of basic shapes, their names, the formula defining the union of them and assigned properties of material (electromagneticProperties) for the shapes.

After that, I have tried to apply the boundary conditions using the function applyBoundaryCondition e.g.

applyBoundaryCondition(emagmodel,"dirichlet", ...
                             "Edge",[5 6 7 26 34], ...
                             "r",250,"h",1);

but I got the error: Unrecognized function or variable 'applyBoundaryCondition'.

Does anybody know why?

"Does anybody know why?"

Do you have the Partial Differential Equation Toolbox installed, and a valid license for it?

Thank you for the link.

Yes, I do have the license nad the Toolbox is installed. Otherwise, I could not use e.g. function electromagneticProperties. Moreover, the shortened result of the ver function is

What happens when you try to perform the Dirichlet Boundary Conditions example from the link Stephen posted? Does it still say Unrecognized function or variable?
