+`Ascent <ascent.readthedocs.io>`_ has been integrated into MFIX-Exa for *in situ* visualization. 
+For codes that have been built with Ascent support, the following inputs must be preceded by "ascent" 
+and specifies the ascent actions for fluid and/or particles. The frequency which these are called 
+is controlled by `ascent_int` or `ascent_per_approx`, see above.
