I use the PDE Toolbox to analysis a discrete geometry, and I want to put the force vector on a point. But I can't define a point through the syntax "loadedVertex". Is there any other option to define the point? thank you!

The function addVertex was introduced in R2019b. You might be running an older version of the MATLAB to get this error.

Thankk you! But when I use the R2019b, I got another error. I can get the VertexID, But I can't put the force on the points.

OK, in that case can you number the number of verteices in the model:
>> gm
Do you see the new VertexID in the plot you make?

Thank you for your answer. Yes, I can see the new VertexID in my model. But I can't solve it with force.

Thank. Now I see the issue. You generated mesh before adding vertex. Do all geometry operation before generating mesh. If you move the addVertex to right below importGeometry, you should not get this error.
