I am aware of several recent papers related to computational issues in strain gradient and other higher order theories. Has anyone tried the software package FEMLAB for such theories ? It purports to solve user defined PDEs. We have only had limited experience with it and I am curious to find out if someone has tried it out.

Pradeep, I have not used FEMLAB for such a purpose but have had good luck with a similar-sounding program "Flex PDE " for solving user-defined PDEs. It is not, however, for strain gradient problems that I have been using it.
