Hello everyone! I'm solving the following task.

You might want to start by doing the tutorials. They'll cover the basics, and explain how, why and where to add some of the above.

I've looked through a lot of videos but no one does functional boundaries. Each uses constant boundaries.

So, not CFD. I have no idea how Mechanical works so will move to the correct part of the forum and leave it with

For the first equation, k is the value of conductivity, right? In Workbench, on the Engineering Data cell, open that and create a material, and set the conductivity to 1.0
For the second equation, use the Pulldown Menu on the Magnitude row of the Temperature Details and select Function, then type the function.
For the third equation, maybe there is a mistake because the second term at x=2 is 4x^3 which would evaluate to a constant, which is fine. Or was that meant to be 4y^3?
Workbench does not allow the Internal Heat Generation to be a function of x and y so you will have to ask someone else how to do that.
