How can I solve this PDE equation?

1 view (last 30 days)
∂c/∂t+Q∂c/∂v=Ri
R1=∑_(i=D)^G▒KFiCf
R2=KFDCF-∑_(i=N)^G▒KDiCD
R3=KFNCF+KDNCD-KNGCN
R4=KFG+KDGCD+KNGCN
I.C.: Ci(v,0)=Cis
B.C.: Q(0,t)=Qin &Ci(0,t)=Ci0

I do not know how to sum over a range of symbols unless the symbols have been ordered in some way. A summation over an unordered set of symbols is denoted by sigma variable_name element_of set; when you have sigma variable_name = value with upper value given, then it is assumed that the variables are orderable and vary by 1 -- e.g., i = N, i = N+1, i = N+2 ... i = G
