Hy Philip,
<p>You probably have some zero velocity neutrons or such huge velocities
that the square gets hawfull (before getting the sqrt), else I can not
figure out how the 'sqrt' can fail in the speed in L_monitor.comp.
<br>You may copy this component locally and change the line #76 so that
it tests the speed norm to be non zero or reasonable value (not huge).
<p>You may also try replacing with the Monitor_nD(options="auto lambda",
filename="...")
<p>Cheers, Emmanuel.
