How to change labels in pde toolbox

Hello everyone,

Is it possible to change the labels when using the pde toolbox?

For example, make face labels correspond to the same faces as the solids below.

clear
files = unzip('wing.zip')

files = 1x2 cell array
    {'straight.STEP'}    {'tappered.STEP'}

% geometry
g1 = importGeometry(files{1});
g1 = rotate(g1,90,[0 0 0],[1 0 0]);
g2 = importGeometry(files{2});
g2 = rotate(g2,90,[0 0 0],[1 0 0]);

% model
wing1 = createpde();
wing1.Geometry = g1;
pdegplot(wing1,"FaceLabels","on",FaceAlpha=0.5)
exportgraphics(gcf,'straight.png','Resolution',300)

wing2 = createpde();
wing2.Geometry = g2;
pdegplot(wing2,"FaceLabels","on",FaceAlpha=0.5)

Hi Geovane,

In the PDE Toolbox in MATLAB, you can change labels to correspond to faces of solids by utilizing the pdetool function. By setting the FaceLabels property to "on" in the pdegplot function, you can display face labels on the geometry plot. Additionally, you can customize the labels further by modifying the properties of the plot.

Here is an example code snippet demonstrating how to achieve this

% Create PDE model

model = createpde();

% Set geometry and plot with face labels

pdegplot(model, 'FaceLabels', 'on', 'FaceAlpha', 0.5);

% Export the plot

exportgraphics(gcf, 'geometry_with_labels.png', 'Resolution', 300);

By following these steps and customizing the plot properties, you can effectively change and display labels in the PDE Toolbox according to your requirements.

Hope this answers your question.

Hi Umar,

Thanks for answering.

It's not clear to me how do I change the labels, for example relabel the F3 face to F4.

Hi Geovane,

If I recall and jog my memory correctly, you can use the set function to update the properties of the object.

Hope this will help resolve your problem.
