[Nek5000-users] Compilation errors when points in an element become large

[nek5000-users at lists.mcs.anl.gov]

Dear Nek devs,

     In the example case "pipe", when I put in lx1=16 and lxd=24 with 
everything else being the same, the following compilation error occurs:

make: *** [nek5000] Error 1

These kind of errors seem to come up whenever I increase lx1, lxd or 
sometimes even lelt and lelg to a large number in other examples too. 
How do i rectify this?
Also what are the functions of lelx, lely and lelz? These parameters are 
not documented on the Nek5000 website.
