Hello dear lammps users and experts,
May i know that there is any way to calculate von mises stress and output in into a dump file?
In the normal way, it must be calculated with a variable command but it is not possible to output a variable into a dump file, as i know so far.
Best regards,
Rouzbeh

that statement is not quite correct. a dump file can output pretty
much any kind of *per atom* data, and thus also atom style variables.
the file format, and thus the dump command, has no provisions to
output any global data outside the timestep and box info.
global data you can capture either as thermo output and then extract
from the log file or use fix print with a file.
