But my concern is that I want to make my simulation more and more accurate.&nbsp;&lt;br&gt;&lt;br&gt;As you know the servers have tiny fans inside and each server supports 6\/7 fans for example and each rack contains several servers. So, the total actual fans are huge and can indeed be impractical to consider all of them due to the complexity and the sheer number of fans.&lt;br&gt;I have 144 racks total:&lt;br&gt;A sample of one rack, showing the back of it with 3 fans to take the cold air from the tiles&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/30-09-2024-1727685805-e2c12a0d-36f4-403b-9dd7-544f5402fec7.jpeg\" alt=\"one of the 144 racks that I have on my project\" width=\"241\" height=\"159\" \/>&lt;br&gt;&lt;br&gt;Another shots, showing the perforated tile and the servers inside the cabinet&lt;br&gt;&lt;br&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/30-09-2024-1727685834-922b9272-dc39-42fd-a1fe-962c1416c8f1.jpeg\" alt=\"\" width=\"381\" height=\"251\" \/>&nbsp; &nbsp;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/30-09-2024-1727685951-0960b2fb-9ff2-4c44-a9c4-72a0f97ad554.jpeg\" alt=\"\" width=\"316\" height=\"312\" \/>&lt;br&gt;&lt;br&gt;So, can anyone suggest some modification to make the simulation better in terms of things that can lead to more accurate results with efficient work. Noting that I use velocity of 3 m\/s and pressure of 30 pascal for each fan but in non containments areas the velocity is very high in some areas of the room because of the fan volume and it doesn&#8217;t reflects an actual scenario for sure. The Heat transfer is quite good but I need to make my simulation more and more accurate.
