dnsFoam boxturb16
 
Hi,

I am trying to run a simulation of a flat channel with periodic boundary conditions streamwise and spanwise. I modified the dnsFoam tutorial case with the respective boundary conditions. I am able to run the case but I get an error when running "foamToVTK":

within every time:

Code:

--> FOAM Serious Error :

    First token could not be read or is not the keyword 'FoamFile'

Check header is of the form:

At some point it stops and delivers this message:

I dont know if this is because I should modify the E.q and E.xy files in some other way or if I'm making any other rookie mistakes. Thanks in advance!
