[CIG-LONG] Cumulative strain history in Gale et alia

[Bradford H. Hager]

Christoph and others-

I'd also be interested in any benchmarking, as well as learning some  
"tricks of the trade" running GALE.

I am running some simple wedge models with viscous and Coulomb  
rheologies.   I find that viscous problems run quickly, and problems  
where the deformation is all by plastic deformation converge, but  
take a lot longer.  However, problems where I'd expect the  
deformation to be mixed viscous and plastic do not converge before my  
patience expires, contrary to my expectation that run times should be  
intermediate between the two extremes.

Also, increasing the tolerance by a factor of 3 can also increase the  
run time by a lot.

Can anyone point me to an explanation of what effects run times?

Thanks,

Brad Hager
