The project was granted special funding from the Academy of Finland earmarked for COVID-19 research.<\/p>\n<p>Open code software comprising about 1,000 lines of code is now nearing completion. The program has been implemented to enable the most challenging types of modeling in three days.<\/p>\n<p>&#8220;For typical flow simulation software, even a supercomputer could easily use ten times as much time on the same task&#8221;, says Vuorinen, who has been working on modeling using a supercomputer during the coronavirus epidemic.<\/p>\n<p>&#8220;Using our software only requires a desktop computer and an efficient graphics card\u2014the kind that is familiar from the world of gaming which draws graphics on the display, and which costs about 2,000 euros.&#8221;<\/p>\n<p><b>Known\u2014but not recognized<\/b><\/p>\n<p>When a person breathes, sings, and speaks, carbon dioxide and aerosols are released into the air from the airways.
