Also the vessel is operated in batch so there are no inlets or outlets (tracer injection is instantaneous).&lt;\/p&gt;&lt;p&gt;To do this I have activated the species transport model and created a mixture template for the water &amp; tracer (tracer &amp; water have same properties). I can see that a new equation has been added for the tracer.&lt;\/p&gt;&lt;p&gt;However I do not know what other steps I need to do before running the simulation, i.e., how do I define the region of cells occupied by the tracer in the tank at the beginning?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392238","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi, I am modelling mixing of two miscible fluids (water &amp; tracer) in an agitated vessel where I want to monitor the concentration profile of the tracer over time at several locations in the vessel.
