Hi, Thanks for your quick reply. Just I wanna know if I can use the interpolated values of velocity at some arbitrary points in the domain (not necessarily the grid points) as the input arguments to theses subroutines.

Error when creating own mesh
by nek5000-users＠lists.mcs.anl.gov 01 Mar '16

01 Mar '16

Dear Neks, I am have attempted to use nek5000, firstly by following some of the examples etc. Now I am trying to create my own simulation, which is based upon the ocyl examples. My efforts simply include creating my own grid points in the .rea file to create a slightly different dimension... I believe I have understood how to define the problem however I continually receive errors when creating the genmap it reads as follows.... Input (.rea) file name: ocyl Input mesh tolerance (default 0.2): NOTE: smaller is better, but generous is more forgiving for bad meshes. 0.2 reading .rea file data ... ERROR: error reading 1 11 24 aborting 510 in routine rdbdry. 1 quit All I have done again is change the dimensions of the elements in the .rea file so I do not see why it would now not work? Thank you for any help in advance, Friedrich.

Hi, Phillip Thanks for your reply, but the dos2unix actually does not help. And I tried a lot to fix it up, including copy existing command from other examples .rea files to eliminate the error that might have something to do with the "CR and LF" stuff (I know little about these line breaks). I am in Ubuntu, should this this be due to the failue of reading restart parameters?he I have attached the .rea file. It would be greatly that you can have a look and give some advice. Thanks in advance. and have a nice weekend! from Allen On 08/29/2015 01:00 AM, nek5000-users-request(a)lists.mcs.anl.gov wrote: > Send Nek5000-users mailing list submissions to > nek5000-users(a)lists.mcs.anl.gov > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.mcs.anl.gov/mailman/listinfo/nek5000-users > or, via email, send a message with subject or body 'help' to > nek5000-users-request(a)lists.mcs.anl.gov > > You can reach the person managing the list at > nek5000-users-owner(a)lists.mcs.anl.gov > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Nek5000-users digest..." > > > Today's Topics: > > 1. restart a case got an error: Error reading initial > condition/drive force data (nek5000-users(a)lists.mcs.anl.gov) > 2.

Hello, Phillip and nekers, Thanks for your help. I think I found the reason. Yesterday, I uploaded the .rea file where the boundary conditions was deleted because I got a warning for the file size exceeding 120 kB. I look into the tutorial today, and find my mistake lies in the fact that I changed the restart options and then I compiled the case files, but in the tutorial it compiles the case files first and modifies the .rea file for restart. And now after following exactly the tutorial it is working, I don't know the exact logics in these differences. (I bet this might be the reason? if yes, can you give some explaination). I never used nek before, so there might be some misunderstanding, but fortunately I got it fixed, this might be tuition for beginners:-) . Thanks again, and I can continue to progress now. form Allen On 08/31/2015 01:00 AM, nek5000-users-request(a)lists.mcs.anl.gov wrote: > 1 PRESOLVE/RESTART OPTIONS ***** > eddy_uv0.f00001

Infinite Prandtlnumber with Nek5000
by nek5000-users＠lists.mcs.anl.gov 17 Aug '15

17 Aug '15

Hi all, I was wondering if it is possible to use Nek5000 for simulations in the infinite Prandtlnumber regime (e.g. planetary mantles). This would require to solve the NS Stokes equation without the time derivative and advection term and the heat equation for T: 1) Solve visc * laplace u - grad p + buoyancy = 0 and div u = 0, where bouyancy depends on a given T field and a Rayleigh number 2) Update T by solving dT/dt + u grad T = diff * laplace T (+ other sources) 3) go back to 1 with the new T field, repeat More realistic models would then use a varying viscosity. I looked at the steady state example (kov_st_state), but this is missing the time depencence via the Temperature. Any hints on the possibility would be much appreciated. Thanks, Jan

These are the parameters for mesh3, but I'm not sure how they work in the code. For velocity and pressure, I would assume we only use mesh1 and mesh2. I'm just wondering is it necessary to set lx3 to be equal to lx1 (if I'm using PnPn-2)? Or does it matter whether it is equal to lx1 or lx2? Hope anyone could help with this. Thank you very much in advance. Best regards, Tony
