Integral over moving region in stationary solver

Hello,
I have a stationary magnetic field and would like to take the integral of H over a moving region inside the simulated domain. This can be done with a moving mesh and selecting the moving domain in the integral operator, but then I need to solve in a time-dependent study. Is there any way of spatially varying the integration bounds without using a moving mesh?
Say that I have a 1D domain and I want to integrate from x=0 to 1 at t=0, but this domain of integration moves with a velocity of t so that at t=1, the integration is from x=1 to 2. The field does not change in time, so I would simply need to vary the integration boundaries without needing to have a time-dependent study.
I found this blog post Integrals with moving limits, but I'm not sure if this will actually give me what I want. Any ideas?
Thank you,
Alexandre

Hi Alexandre,
Is the shape of the region on which you want to perform the integration simple enough that you could carry the integration on the entire geometry but use a boolean expression in the integrand, like in the attached file?

Hi Jeff,
This is exactly what I wanted and is much more elegant than what I was envisioning.
Thank you,
Alexandre
