I am facing few issues while performing simulation.<\/p>\n<ol>\n<li>I first created a case setup in fluent and initialized it and saved it as .cas file.<\/li>\n<li>Later in Rocky window i dragged and dropped fluent setup to Rocky setup, linking them using &#8216;unresolved 2 way coupling&#8217; option.<\/li>\n<li>I uploaded the geometry in rocky geometry.<\/li>\n<li>Created particles, setup boundary conditions.<\/li>\n<li>After solver setup, I started simulation, which opened the fluent and both fluent and Rocky started solving simultaneously.<\/li>\n<li>After calculation was complete, when I tried post processing it i was able to see simulation of particles in the domain.&nbsp;<\/li>\n<\/ol>\n<p>&nbsp;Issue 1: But then why workbench is still not showing the calculation as complete.
