[Nek5000-users] Periodic B.C and Genmap Issue

Thu Mar 10 08:46:43 CST 2016

Hi Paul,

It is looks like that the n2to3 not generate the 3D  mesh with periodic
boundary conditions correctly by rotating.  First I tried to generate a 3D
mesh, then after applied genmap it appears the similar error.

Following the discussions some years ago, it seems I need to update the
genmap.f,  Have you update the new version, or Would you like to post the
genmap.f again?
thanks!

n2to3

 This is the code that establishes proper

 element connectivities, as of Oct., 2006.

 Input old (source) file name:

box

 Input new (output) file name:

boxss

 For ASCII output only: 0; For .rea/.re2: 1

0

 input number of levels: (1, 2, 3,...; < 0 for circular sweep.):

-20

 input z min:

0

 input z max:

90

 input gain (0=custom,1=uniform,other=geometric spacing):

1

 This is for CEM: yes or no:

no

 Enter Z(5) FLUID boundary condition (P,v,O,ect):

P

 this is FLUID cbz: P  P   <---

Input mesh tolerance (default 0.2):

NOTE: smaller is better, but generous is more forgiving for bad meshes.

Hi,

Yes, got it now. I don't know why it wasn't working either. I use the
same thing to compress files, either way it's good now. Thanks Paul.

Hi Michael,

not sure why gunzip didn't work - it worked here... but I've
put the unzipped version in:
www.mcs.anl.gov/~fischer/genmap.f

Let me know if that works for you.

Cheers,

Paul
