Solved my own problem. It does indeed appear that all metadata that used to follow the volume values has been removed.



Original question below:



Hello,


I had previously written a python script to extract data from SU2 binary restart files.


The script worked for v. 6.2 and below, but I now seem to have problems with restart files from v. 7.0 and above.


I saw on the guide that the ASCII format has changed (certain metadata is no longer written). Does this also apply to the binary file format?


Is there a guide/specification on the binary restart file format as of version 7.0? If so, can someone point me to it?



Thanks!

Hi Paul,

Have you solved this problem? I am struggling to read the restart file with python. It would be greatly appreciated if you could give me some help on this.

The restart file is stored in binary format. For steady bidimensional simulations, it's structured in the following way:

Offset Size Type Comment
0x00 0x4 int Magic, 0x82BEC
0x04 0x4 int Number of primary properties
0x08 0x4 int Number of data entries or number of mesh vertices

Following this header, at offset 0x14, you have the properties names in string format, each one with size 0x21.
Then there are the flow data, stored in double float format following the vertex order of your mesh (ie, first entry is related with vertex 1, second entry to vertex 2,...). For each vertex, the flow data is organized in the sequence presented in the properties names section.

Thanks for your answer! It is quite helpful.
