<p>I would like to simulate how the overall concentration of a tracer varies in a large fluid domain (like a flume) through both mixing due to a set of rigid structures and through the consumption of the tracer by some of these objects. I have an aggregation of 12 objects, five of which have been turned into pumps with an internal volume and set inlet and outlet boundary conditions (with a velocity inlet and zero pressure opening for the outlet). I would like to set an ambient level of tracer in my larger velocity inlet for the whole rectangular fluid domain and then have the fluid enter the small inlet with that ambient level of tracer but with a level of consumption (i.e. 10% of what enters) at the outlet. I am not sure how to do this given the current options for adding in an additional variable to use as a tracer. Does anyone have any suggestions as to how I might do this? I have included a photo of my geometry, the smaller inlets and outlets are highlighted in green. \"\"<\/p><p>\"\"<\/p><\/p>\n","protected":false},"template":"","class_list":["post-389857","topic","type-topic","status-publish","hentry","topic-tag-cfx-tracer-simulation"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
