In the current implementation, set.execute does not support an input
dt < 1 second(i.e.dt.dtype("ns")because we initialise theparticledata.dt.dtypein seconds, so any input dt smaller than that will be0(and hence the code will go into an infinite loop)Now, we could of course set the default
particledata.dt.dtypein"ns", but the disadvantage is that all thesedts will then be very large numbers. But perhaps a nicer way is to let users update theparticledata.dt.dtypeonly when that is necessary (i.e. when their inputdtis sub second), This PR proposes that.This PR addresses #2241
