We are using COMSOL to simulate lasers irradiating a biological tissue with certain vales of scattering and absorption coefficients. Till now, we had used a constant point source by putting 'u_test' in the weak coefficient of point settings. But now, we want to modulate the intensity(or amplitude) of this point source sinusoidally. I am not able to find any ideas anywhere. Please Help, very urgent.<br /> Tue, 16 Mar 2010 09:54:18 +0000 3877.1268733258.10093
