Hi,

I am using foamToVTK on my Ubuntu machine (I need to export the VTK folder to postprocess on another machine).

On version 1.5, if I have too many time folders in my case (around 50 it seems) I get this error notification:

--> FOAM Serious Error :

FOAM aborting

Abandon

Can anyone help ? Thank you ?

only 50? thats nothing.

disk full perhaps?

1 create a bck directory,
2 move the last timestep to the bck-dir.
3 run foamToVTK
4 if it fails go to 2
5 it works - you've found the directory causing the problem.

or move all timesteps to the bck directory and then move them back 1 by 1 until it fails.

It could be that you've lost the connection for a while to the disk while writing the data (if you're working agains an nfs disk or similar)

[johndeas]

I have found a workaround: I launch

foamToVTK -time xxx

using a script, for all my timesteps. It works, so the problem really is the number of time directories, and not a specific one. I have the same problem with both redhat and ubuntu.

Hi John,

Very strange. Do you have sample case that goes wrong? Or can you just do an 'ls' so we can see what time directories you have.

[johndeas]

I tried at home outputing 75 time directories and importing them without problem to paraview. I though it was related to my linux distro but it is not then. I will try to isolate more the problem then report here.
