Well, no. I got a 20GB log file when nstlog was 1000. When I changed it to 10000, the log file was about 1 MB after a few minutes of simulation which means that it will be in GBs in a few days.<br><br><div class="gmail_quote">

You've set the frequency of writing to log file as 'nstlog = 100000'. <br>Given that 'nsteps = 100000000', you're writing to the log file only 1000 times. Do you get a 20GB md.log file with these settings?<br>

Hi,<br><br>I am having some problem in my simulations related to log files. The file sizes are enormous, its like after 3 days of simulation I had a 20 GB md.log file.
