[aspect-devel] Geometry dimensions affect convergence?

this is because we are not setting the length_scale in
geometry_model/box.cc correctly. Can you update to r1344 and try again

We've noticed that solver convergence is sensitive to the dimensions of the model and for some models the size of the geometry will determine whether the solver converges or not. I've attached two parameter files - the good one runs to completion while the bad one fails to converge on the first step - note that parameters other than dimension are also changed but everything is still within ranges expected of an Earthlike mantle. Can anyone give suggestions about why this happens and what we can do to fix it?
