Hello everyone,<\/p>\n

I’ve been using a macroscopic particle model (MPM) to create a group of particles (1 cm. diameter<\/span>) inside a cylinder.<\/span><\/p>\n

\"\"<\/p>\n

The whole fluid inside a chamber is only air.<\/p>\n

After I initialized a system, I checked a contour of a MPM-volume-fraction. Everything went well.<\/p>\n

\"\"<\/p>\n

Then, I checked a contour of air <\/span>volume fraction. I found something strange. The air volume fraction was 1 but it should not be like this.<\/span><\/p>\n

\"\"<\/p>\n

I think the MPM volume fraction was already recognized by the software. My question is why the air volume fraction is full-on plane 3? <\/span><\/p>\n

I mean should it be blank in the area that was occupied by particles?<\/p>\n

Your help is greatly appreciated.<\/span><\/p>\n","protected":false},"template":"","class_list":["post-238803","topic","type-topic","status-closed","hentry","topic-tag-mpm"],"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
