Can COMSOL handle differential terms with a value greater than 2? Many of the high order PDE processing methods found on the Internet by COMSOL are realized through intermediate variables to reduce the order.However, this approach often involves the definition of initial values and boundary conditions. I noticed that COMSOL seems to have its own nine-node quadrilateral element shape, and it can also make a high-order definition of Lagrange element in the discrete window of weak form.Is there a element with C1 continuity that can be used to solve higher order terms?
