Sir, I am using Comsol multiphyics5.3a license version 10677635 in our institute for the simulation of our piezoelectric energy harvester. In the time-dependent solution, we are using body load physics as the external load. Till now we are giving the sinusoidal time-varying load in the simulation. The body load expression is " solid.rho*g_const*sin(2*pi*100[Hz]*t) " as the load per unit volume. Now we want to give the impulsive force in the body load setting and want to see the effect of the force impact on the transient simulation of the piezoelectric energy harvester. I request you to please help me with impulsive body load expression (Impact based force).
