I have attached some images of the settings that I have tried most recently. Ideally, the flow rate should be around 0.125 kg\/s. Could you wonderful people help me get an understanding of how the flat fan model works and what parameters are essential to the success generation of this DPM simulation.<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/06-02-2024-1707230903-mceclip0.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/06-02-2024-1707230930-mceclip1.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/06-02-2024-1707230964-mceclip2.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/06-02-2024-1707230987-mceclip3.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/06-02-2024-1707231025-mceclip4.png\"><\/p>\n","protected":false},"template":"","class_list":["post-349398","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"I&#039;ve been trying different settings to try to get this flat fan spray model to work, (Increasing and decreasing mass flow rate, fluid flow time step, and orifice width), yet nothing seems to work.
