I want to simplify G_{ti} expression in ...

Maple 12

I want to take v_{r} , v_{theta}, and v_{pi} common out of this expression and I want to simplify in a more simplify way. The maple sheet is attached below:metriccalculaions.mw

G[ti] := -(v[r]*`cos&theta;`*`cos&phi;`+v[r]*`cos&theta;`*`sin&phi;`+v[r]*`sin&theta;`)*rho*(-c^2+(1-A)*(v[r]^2+v[theta]^2+v[phi]^2-(v[r]*`cos&theta;`*`cos&phi;`)^2-(v[r]*`cos&theta;`*`sin&phi;`)^2-(v[r]*`sin&theta;`)^2))/(A*c^3)

Maple 12

solve((&PartialD;(-    &nabla;(f) ))/(&PartialD; t)+((DotProduct(v[0],&nabla;f))*(1-e(DotProduct(B,Omega)))+(c[s0]^(2)*rho[1])/(rho[0])(1-e(DotProduct(B,Omega)))+e(CrossProduct(&nabla; f,B))*Omega-e((DotProduct(-&nabla;f,Omega))*(DotProduct(B,&nabla;)))*(-&nabla;f)+e(E)*(1-(DotProduct(B,Omega)))+e^(2)(DotProduct(E,B))*Omega-e*((CrossProduct(E,Omega))*(&nabla;(-&nabla;f)),rho[1]);
