Meshing interpolated curves

I have a simulation where my geometry is an interpolated curve. The meshing for that feature is really fine and detailed:

Are there any tricks I can use to reduce the required meshing? Even if it lowers the simulation accuracy, I'm willing to do quicker runs and then more thorough simulations once I'm in the ballpark.

I'm running 5.3 by the way.

Thanks!
