USRSRC-problem

Sudarshan

Dear Friends, I want to link the usrsrc routine with the mail CFX-Tascflow. The following problems I am facing. 1.To add source terms into the species equations we need to add "ILABEL" variable in the subroutine such that we can put i=1 to PHIn true for putting the source terms.( which is not available in default). 2. I want to add few more local subroutines to calculate locally the reaction rate, entahlpy, entropy and other properties, for which I has written the subroutins, but as soon as call these local subroutines into the USRSRC subroutine to add the source terms like reaction rate, the programme doesn't proceed further. It automatically stops there. please help me....... Regards Sudarshan
