This file calls (line 1097) the "fPltZone_Convective_Gain" function (originally defined in "src/esruplt/Plt_zone_gain_coupling.F") to link the plant losses and its environment. The component losses is handled by "fPltComp_Gains(iComponent, iConvective )" parameter for any of plant components. But, its value is not assigned for explicit plant components. So, I wonder that explicit plant losses to the containment is addressed in ESP-r. <o:p></o:p></span></p> </div> <div> <p class="MsoNormal" style="background:white"><span style="font-family:"Calibri","sans-serif";mso-fareast-font-family:"Times New Roman";color:black"> <o:p></o:p></span></p> </div> <div> <p class="MsoNormal" style="background:white"><span style="font-family:"Calibri","sans-serif";mso-fareast-font-family:"Times New Roman";color:black">Is any other method used to add losses in zone casual gains?<o:p></o:p></span></p> </div> <div> <p class="MsoNormal" style="background:white"><span style="font-family:"Calibri","sans-serif";mso-fareast-font-family:"Times New Roman";color:black"><o:p> </o:p></span></p> </div> <div> <p class="MsoNormal" style="background:white"><span style="font-family:"Calibri","sans-serif";mso-fareast-font-family:"Times New Roman";color:black">Regards,<o:p></o:p></span></p> </div> <div> <p class="MsoNormal" style="background:white"><span style="font-family:"Calibri","sans-serif";mso-fareast-font-family:"Times New Roman";color:black">Rasoul<o:p></o:p></span></p> </div> </div> </div> </body> </html>
