But I dont know how to deal with this definite integral. Any ideas? Code: fvScalarMatrix nEqn ( fvm::ddt(n) + fvm::div(phi1,n) == ???? ); $\frac{{\partial \left( {{\rho _d}{N_d}} \right)}}{{\partial t}} + \nabla \cdot \left( {{\rho _d}{u_d}{N_d}} \right) = \int\limits_{0.5}^1 {f\left( \varepsilon \right)d\varepsilon }$
