ffa2engold and lambda2 problems
 
Hello

I am trying unsuccessfully to convert my results to ensight format incuding lambda 2. To output is as follows:

[x_ollbo@neolith1 scania_fine_EDGE_steady_200g]$ ffa2engold -cb -l2 ../fine_extruded.bedg fine_extruded.aboc fine_extruded.bmsh
fine_extruded.bout L2_inst_fine
ffa2engold version $Rev: 2379 $ is starting...

Processing steady grid and steady solution.

All EnSight Gold data files will be stored on C Binary format.

Adding lambda2 field.

Reading mesh file "fine_extruded.bmsh".

Update mesh to multi-region format

-- Done reading.

Analyzing mesh data
-- Warning! There will be a loss in precision, since only
single precision is allowed in EnSight Gold format.
Writing file "L2_inst_fine.geo".
-- Done analyzing.

Reading solution file "fine_extruded.bout".

Update solution to multi-region format


Solution already in multi-region format
-- Done reading.

Update boundary to multi-region format


BOUNDARY already in multi-region format

ERROR IN MODULE FFA, ROUTINE "FFFSDS" !!!
--- DATASET NOT ASSOCIATED, SEARCHING FOR n_edges ---


ERROR IN MODULE FFA, ROUTINE "IVALUX" !!!
--- STRING "n_edges" NOT FOUND ---

STOPPING EXECUTION!!
[x_ollbo@neolith1 scania_fine_EDGE_steady_200g]$

I have done this before but it was quite a while ago, what am I doing wrong? I am using Edge 5.2 (r2568) both for the calculation and for the attempted postprocessing. Any help would be greatly appreciated!

mvh, Olle

were you able to solve your problem?

No, I have not been able to solve this. To be honest, I have not started looking through the code for ffa2engold yet which I suspect will be necessary as I do not understand the error message.

The string "n_edges" is present in the *.bedg file which I assume this part is about:

BOUNDARY already in multi-region format

ERROR IN MODULE FFA, ROUTINE "FFFSDS" !!!
--- DATASET NOT ASSOCIATED, SEARCHING FOR n_edges ---


ERROR IN MODULE FFA, ROUTINE "IVALUX" !!!
--- STRING "n_edges" NOT FOUND ---

But, as I wrote, this error does not make sense to me so I need to understand what ffa2engold does when it gives this error. Right now I do not have time for this but I will update the thread when I do.

Sure, keep me up on your progress, I'll check it out too and if I find something I let you know.

Just checked the ffa2engold and seems to be working fine for me, this is an output. Check your bedg file with ffalist:

ffa2engold -cb -l2 Mesh.bedg Mesh.aboc Mesh.bmsh Edge.bout test2
