Dynamic mesh for walking manikin in FLUENT

soriyoshi · January 14, 2015, 05:02

Hello~
How could I define the movement of human legs in FLUENT?(the model in the picture is from the paper by Brian A. Edge http://fluidsengineering.asmedigital...d=1430217#tab2 )
Attachment 36528

At first, I assume the two legs to be rigid body, but how to describe them since their movement combines rotation and moving forward?

If I ignore the movement of legs, can I contain the manikin surface in a small zone within a room model, so that the cells adjacent to human surface does not update? If so, should I use DEFINE_GRID_MOTION or DEFINE_GEOM or another macro? If sliding mesh is possible, I think it's much easier for mesh updating....

Thank you very much!

I‘m afraid I have no idea...Maybe you can search CFD courses in India on Youtube and figure out which institute they belong to....
