Hello everyone, I am using the dynamic mesh method to simulate the dipping process of a pipe into hot melts. When the pipe is dipped into the melts, it will be melted due to high temperature, and the melted parts will flow unrestrictedly in the melt.<\/p>\n

I am facing the following problems:<\/p>\n

    \n
  1. if I set the pipe as a solid zone, the UDF "DEFINE_CG_MOTION" can well describe the movement of the pipe, however, I can not simulate the melting process of the pipe (melting and solidification model needs fluid zone setting);<\/li>\n
  2. if I set the pipe as a fluid zone, the UDF "DEFINE_CG_MOTION" can not give the velocity of the pipe zone, and the pipe zone will deform, and can not keep its shape.<\/li>\n<\/ol>\n

    Could you give me some comments how to do this case? Thank you in advance.<\/p>\n","protected":false},"template":"","class_list":["post-166204","topic","type-topic","status-closed","hentry","topic-tag-dynamic-mesh","topic-tag-meltingandsolidification-1"],"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
