|
<P>Perform time integration to update internal energy and local density, but not
|
||
|
|
position or velocity for atoms in the group each timestep. This fix is needed
|
||
|
|
for SPH simulations to correctly time-integrate fixed boundary particles which
|
||
|
|
constrain a fluid to a given region in space.
