Hi I am trying to see if there is FindFace command or something that allows me to see the Faces linked to a cell in the pde toolbox. I want to get away from having to assign the boundary conditions to the appropriate Faces everytime I change a parameter by plotting the geometry. Thanks, Best regards, Souvik

Hello Souvik,
Did you get the solution for your problem? I am facing the same. Thanks.

Hi,
There is an undocumented function, findFaces within the PDE Toolbox that can list the IDs of the faces associated with a cell. Below is an example of its usage:
% create a PDEModel object
pdem = createpde();
% create geometry
pdem.Geometry = multicuboid(1,1,1);
% find faces associated with the Cell
pdem.Geometry.findFaces('region','Cell',1)
Please note that the findFaces function is only an internal function and does not have a fully developed API for it.

Is this a function which is likely to be removed in future releases given it is undocumented?
