[Nek5000-users] Definition of variables in the .usr file?

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

Dear Johan,

Virtually _all_ the variables are available because of the include 'TOTAL' statement.

Geometry is in arrays xm1,ym1,zm1.   N^3 x Nel is the data layout for all arrays, save
for surface variables such as unit normals and surface area of each face of each element.
(unx,uny,unz,area).

Paul

Dear All,


Is there any documentation of all variables that I have available in the .usr file?


For example, in the User Guide it is explained you to modify a mesh for a straight pipe into a pipe with a width that varies along it.

You use then


* The variable "ntot". Which I guess is the number of vertices, but i it?

* The variable "ym1", which seems to be a 4D tensor. Here you change the element ym1(i,1,1,1) for i = 1,ntot. Is this the y-position of the verices? What alse does ym1 contain?


These and other variables are variables that I would appreciate to know the definition of. Is it available somwhere?


Best,


Johan
