Some questions have arisen regarding the flow of the molten pool.<\/p>\n<ol>\n<li>Under normal circumstances, there should be two vortex currents in front of and behind the molten pool, but why did they not appear in my simulation?<\/li>\n<li>&nbsp;Simulation setting: the surface tension of the negative surface tension gradient is set in the UDF; Gaussian laser movement speed is set to 25000mm\/s.I would appreciate any reply!
