Hello Dean and Klaus,

Thank you for your e-mail, now it’s clear to me what happened when I doubled the dimensions. It’s fixed now.

Best,
Ian

So you don't get the proper initial state.  An easy way to fix this is to change lrefine_min.  So, for example, if you double the linear size of the domain, by adding lrefine_min=2 to your parameter file, the base grid cell size is the same when the simulation starts constructing the initial condition.
