Hello Jana, it is a good idea to run things interactively from VMD using
QwikMD while learning. However, you will get the most out of the existing
resources if the MD simulation runs unattended in the form of chained batch
jobs.
That means using the information from the log of your interrupted job to
estimate a number of steps that will fit within your job's walltime. You
can then for each new job set the value of outputName to something unique
to that job:
https://www.ks.uiuc.edu/Research/namd/2.14/ug/node12.html#SECTION00062200000000000000
Then the next job will use binCoordinates, binVelocities and extendedSystem
to load the output file of that previous job, while using a distinct
outputName, and so on.
Giacomo
