Action: FLUSH

Module	generic
Description	Usage
This command instructs plumed to flush all the open files with a user specified frequency.

Further details and examples

This command instructs plumed to flush all the open files with a user specified frequency. Notice that all files are flushed anyway every 10000 steps.

The input below uses the FLUSH command to get PLUMED to flush all the output files every 100 steps

d1The DISTANCE action with label d1 calculates the following quantities:
 Quantity   
 Type   
 Description  
d1
scalar
the DISTANCE between this pair of atoms: DISTANCECalculate the distance/s between pairs of atoms. More details ATOMSthe pair of atom that we are calculating the distance between=1,10
PRINTPrint quantities to a file. More details ARGthe labels of the values that you would like to print to the file=d1 STRIDE the frequency with which the quantities of interest should be output=5 FILEthe name of the file on which to output these quantities=colvar1

The PRINT action with label  calculates somethingFLUSHThis command instructs plumed to flush all the open files with a user specified frequency. More details STRIDEthe frequency with which all the open files should be flushed=100

d2The DISTANCE action with label d2 calculates the following quantities:
 Quantity   
 Type   
 Description  
d2
scalar
the DISTANCE between this pair of atoms: DISTANCECalculate the distance/s between pairs of atoms. More details ATOMSthe pair of atom that we are calculating the distance between=2,11
# also this print is flushed every 100 steps:
PRINTPrint quantities to a file. More details ARGthe labels of the values that you would like to print to the file=d2 STRIDE the frequency with which the quantities of interest should be output=10 FILEthe name of the file on which to output these quantities=colvar2

This command is useful for preventing data loss that would otherwise arise as a consequence of the code storing data for printing in the buffers. Notice that it will always flush all the open files and that the location where put this command in the input does not matter. In the input above, for example both colvar1 and colvar2 are flushed every 100 steps.
