<P>IMPORTANT NOTE: The last point means that you cannot restart a
|
||||
simulation with rigid bodies using the
|
||||
<A HREF = "read_restart.html">read_restart</A> command and use the same <I>infile</I> of
|
||||
rigid body attributes as input for the 2nd simulation, if the rigid
|
||||
bodies have moved or rotated. Instead, you need to produce a new
|
||||
<I>infile</I> that reflects the correct attributes for each rigid body at
|
||||
the time of restart. We are thinking about a good way to make this
|
||||
process easier.
|
||||
<P>IMPORTANT NOTE: If you use the <I>infile</I> keyword and write restart
|
||||
files during a simulation, then each time a restart file is written,
|
||||
the fix also write an auxiliary restart file with the name
|
||||
rfile.rigid, where "rfile" is the name of the restart file,
|
||||
e.g. tmp.restart.10000 and tmp.restart.10000.rigid. This auxiliary
|
||||
file is in the same format described above and contains info on the
|
||||
current center-of-mass and 6 moments of inertia. Thus it can be used
|
||||
in a new input script that restarts the run and re-specifies a rigid
|
||||
fix using an <I>infile</I> keyword and the appropriate filename. Note that
|
||||
the auxiliary file will contain one line for every rigid body, even if
|
||||
the original file only listed a subset of the rigid bodies.
