[Mesa-users] resolution study

[Francis Timmes]

epicycles have a long history. 

if it were easy to take results from the restricted range that 
explicit multi-d hydrocodes can explore and mold them into forms 
suitable for some/many/all aspects of stellar evolution, it probably 
would have been done by now. so its a hard problem awaiting copernicus.

There is a history of introducing new, additional parameters for each new test; It might be good to have a wide-ranging and critical look at algorithms and tests, to decide what we think we really know and what we merely fit by parameter adjustment.
