[Libmesh-users] MeshFunction

[Ataollah M. <am...@ti...>]

Dear all,

Can someone please briefly explain how to use MeshFunction to me? I've been digging the mailing list archives and ./src/error_estimation/exact_error_estimator.C to understand it but I'm still hazy on how it use it? 

This is what I intend to do I want to get the L-2 projection of a solution on a side of a 3-D mesh on 2-D mesh. 

PS: feel free to comment if you think there is better way to go about doing the L-2 projection from 3-D to 2-D.

Best,
Ata
