Dear all
Can we write third or fourth-order derivatives in FreeFEM?
However, it is showing identifiers errors while writing third-order derivatives ( like dxxx( u ) ) .
Kindly suggest me in solving this issue.

Applying the Greens theorem multiple times will reduce the degree of PDEs term.
It solved my problem.
