<div>Dear All,</div>
<div> </div>
<div>So I have been doing membrane simulations on a small (really small) node for a few months, and was able to get in a few hundred nanoseconds of time. I now have added 4 inositol lipids, and repeatedly encounter some errors as follows.</div>
<div> </div>
<div>I set the time in the eq for 0.0005 and it runs about 25000 steps. I then move up to a normal sim at 0.002 and it runs about 25000 steps then crashes with a particle moved to far error. On inspection, these vary each time, but are always a membrane lipid /cholesterol or inositol atom, usually trying to move ithrough a periodic boundary temporarily? I then run the sim again (continuation) for 25000 steps at 0.0005 again then it crashes again with the same eror. I then Switch back to 0.002 as a continuation, and the same. I have done this for around 10 ns now? I woundered if there were any suggestions, as it makes it impossible to run a simulation unless you baby sit it constantly, and precludes submitting it to a server? Please excusse my spelling.</div>
