he problem to reduce the dynamic
range of the numerical coefficients, but doing so sometimes leads to undesirable
effects on the solution. It is better to avoid scaling issues during the modeling
process. Don&#8217;t mix values of wildly different magnitudes, such as <tt class="docutils literal"><span class="pre">1e-3</span></tt>
and <tt class="docutils literal"><span class="pre">1e20</span></tt>. Even better, try to avoid any numerical values (both in fixed parameters
and likely values of the variables) th
