Well said. In the case of antenna modelling software, we need to
remember that iterative floating point algorithms are notorious for
stability problems and error accumulation problems. Some problems
are more subtle that my favorite CAD program error message, this
from a logic design rule checker for ECL:
ERROR: 2*10^9 terminations resistors on net: <xxx>; limit is 2.
