Hi,
From a pedagogical point of view, this shows how you as a user can modify the equations used to create for example stiffness matrices and load vectors.
From a techincal point of view, this is a way to include thermal expansion by modifying the expressions for how strains are computed in the case that your license does not have it as a built-in feature. If you have a licence for the Structural Mechanics module or the MEMS module, then it is of course much more convenient to use the built-in Thermal Expansion feature. There are other variants if the same tutorial showing this, as discussed in https://www.comsol.com/blogs/performing-a-multiphysics-analysis-of-a-thermal-microactuator/.
Regards,
Henrik
