checkpoint

write a MESHFREE resume file after the end of the current time step and terminate MESHFREE (parallel reading of signal file)

This writes out a resume file (named .resume) which is like a regular restart file, but with special meaning. The file is not located in the result directory specified by SAVE_path like the regular restart files. Instead, the resume file is written to the directory where MESHFREE is executed.

If at the start of MESHFREE, a resume file is available in the current directory it will be used. MESHFREE will not start from the beginning and restart numbers are ignored as well.

Alternatively, a file named .checkpoint can be written to the current working directory of MESHFREE.

A third option of triggering writing of a resume file, even dependent on the simulation result, is given via the EVENT %EVENT_WriteResume%.

Note: Do not run several instances of MESHFREE from the same directory when using the checkpoint/resume feature!
