How to specify the integration order/number of integration points per element in a PDE module?

Make sure that Equation View is active. Under, for example, a Weak form PDE node, look up Weak Expressions in Equation View. There, you can modify the Integration order text field.

Hi Henrik, thanks very much, as I found before, is it only possible in weak form that one can change the integration order? If so, PDE modules except the 'weak form' module show explicit equations while leaving the weak form completely blank, then can we still change the order?
