Johnny Qin Guest Posts: n/a	I want to define a mass source wich is a function of the change rate of pressure. i.e. dm/dt = K*(dp/dt). Here I need to use the previous step pressure C_P_M1(c,t). but from the macro DEFINE_SOURCE(source,c,t), I can not access to the previous variables. what should I do? Thanks in advance for your suggestion.
