<p>Manos,</p>
<p> An invalid floating point error is a math error like dividing
by zero or taking the log of a negative number somewhere in the
code. It happens in parametric studies sometimes when an
unrealistic combination of parameter values is being run. If such
a problem occurs you can get the project (*.tpf) or the *.dck of
that particular configuration in a parametric run and send it to
your distributor so that they can find the spot in the code so as
to better handle the error. It may be that the simulation will
still generate an error and stop but it should not do so with such
an unhelpful error as an invalid floating point error.</p>
<p>kind regards,</p>
<p> David</p>
