Abstract: Numerical simulations of the solar chromosphere have become increasinglyrealistic over the past 5 years. However, many observed chromosphericstructures and behavior are not reproduced. Current models do not show fibrilsin Ca II 8542, and neither reproduce the Ca II 8542 bisector. The emergentH-alpha line core intensity computed from the models show granulation insteadof chromospheric shocks or fibrils. I discuss these deficiencies and speculateabout what physics should be included to alleviate these shortcomings.
