[Libmesh-users] hierarchic elements

[David K. <dav...@ba...>]

Hi,

I've been trying to have a play with libMesh's hierarchic finite  
elements on a simple square mesh but I'm not sure what is required to  
get them working. What kind of a mesh does one need to generate in  
order to do, say: "system.add_variable("u",FIRST,HIERARCHIC)"

Cheers,
Dave
