Hi everyone!
I have a series of dump files which have time and unit information in the header. My question is, can read_data read time and unit in the header? If so, what is the appropriate command?
I want to export time and unit which is read from the dump file. After I read the dump file, asking for time and unit results in error (dump_modify DumpName time yes units yes) !

yours sincerely
Peter

my dump file:

The answer is no. In multiple ways and for multiple reasons.

  • read_data cannot read dump files, only read_dump
  • units must be set before the the simulation box is created, but read_dump must be called after and does not read the time either
  • you cannot make up keywords and options that are not documented. Anything in your input that is not mentioned in the corresponding documentation must produce an error.
