Hi Spencer, thanks for the command. I was able to merge partitions with it, and convert to VTU. However, some problems show up for highly partitioned cases. I attached an example for two cases merged from p=2, and p=100 (p number of partitions). The contours are the mean spanwise vorticity, extracted with the slightly extended meanmode-module that I wrote. In the case of p=100, there are clear oscillations in some areas. I didn't observe any oscillations for velocity and pressure fields in any cases. So, I guess calculation of derivatives giving problems in highly-partitioned case. I was wondering what could be the reason for this. Thank you very much in advance for any feedback. Best, Asim On Mon, Nov 21, 2016 at 7:29 AM, Sherwin, Spencer J < s.sherwin@imperial.ac.uk> wrote:
HI Asim,
If you put all the files into a directory called meanField.chk/
The only thing you then need in this directory is a file called info.xml which tell you which partitions contain which elements. This can be generated from FieldConvert using
[image: page98image37800]
FieldConvert --nprocs 10 file2.xml file2.fld/Info.xml:info
There should also be some details about this in the user-guide in section 5.5.1 (user-guide-4.3.2.pdf).
I hope this helps.
Spencer.

Dear all,
Due to memory limitations, often I have to partition large data files using something like
FieldConvert --part-only=100 config.xml fields/field_1.chk
, and postprocess them piece by piece:
FieldConvert -v -m meanstats config_xml/P000000"$p".xml fields/field_1.chk meanFields/meanField_1_p"$p".fld
In the case of meanmode module for example, the output is a collection of many small files associated with partitions, which can be analyzed piece by piece. I was wondering if there is a way to merge the outputs back into one piece again like one piece fld file.
Any feedback is appreciated.
