[Nek5000-users] problem with closed internal boundaries

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

Hello Neks,

I'm trying to model a flow past an obstacle in a channel. As a first step I would like to do a 2D simulation. 
I'm encountering some problems during the geometry data generation in the nek5000 execution : it looks like the program can only generate NaN values although genmap seems to work well on the .rea file. 
I can also reopen the rea file with prenek without any problems.

Do you have any idea what is going wrong here?
Is it problematic to have a closed internal boundary condition?
Thanks in advance for any help.

Best,


Michael B
