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.
