remove negative part of sinewave

Does anyone know how to remove or filter the negative part of sine wave?
I want to simulate the behaviour of electric field line in electrostatic physic when the AC source is used as the input at the boundary selected. So, I define the function of sinewave in definition and it works when I run it with the study step is 'stationary' for the result of surface of 2D plot.
However, the result that I got only contain the negative value to zero , which I thought it could be from the sinewave. But, I want the result become zero to positive value.
So, I'm trying to filter the negative value of the result of surface of 2D plot by using parameter sweep and add another study step 'time dependent study'.
I tried to sweep parameter 't' which is already defined earlier by entering the parameter value range(0,1,10) but it cause an error that appears 'No eigenpair solution selected'.
What it is mean by the 'No eigenpair solution selected' ?
or is there other methods that we can use to remove the negative part of sinewave?
