<p>Michel,</p>
<p> The getNumericalSolution() and setNumericalValue() routines are
not specific to the battery component. They are used to solve
differential equations numerically when the equation cannot be put
into the form dX/dt = aX + b (where a and b are constants over the
timestep). The dX/dt = aX + b form can be solved analytically by
calling the solveDiffEq() subroutine. For additional information
refer to the 07-ProgrammersGuide manual</p>
<p>kind regards,</p>
<p> David</p>

<div>Hi all, <br>
</div>
<div><br>
</div>
<div>I am trying to use the lead-acid battery component
(Type47a) in TRNSYS but I have a hard time understanding what
the "Call SetNumericalDerivatie" and "GetNumericalSolution"
functions are doing when using the battery in mode 1.</div>
<div>Can someone perhaps explain this or direct me towards an
example?</div>
<div><br>
</div>
<div>Thanks in advance!</div>
