<p>Hello there,</p>
<p>I am trying to compute certain equation, but I am constantly getting the following error:</p>
<p><br>
</p>
<p></p>
<div>[ TRNSYS Message 5 : The TRNSYS Program attempted to evaluate an EQUATION that has a division by zero. Please check the EQUATION formulation and re-run the simulation</div>
<div> Reported information : EFF_ENERGY ]</div>
<div><br>
</div>
<div>I made sure to calculate the equation only when the denominator is positive as follows:</div>
<div><br>
</div>
<div>[ <span style="font-size: 12pt;">Eff_energy = GT(m_H2,0)*(P_load+Q_heating+Q_DHW+Q_cooling)/(m_H2*LHV) ]</span></div>
<div><span style="font-size: 12pt;"><br>
</span></div>
<div><span style="font-size: 12pt;">Any help would be appreciated...</span></div>
<div><span style="font-size: 12pt;">Regards.</span></div>
