help:error of dynamic mesh
Hi, my friends:
There is a mad error in my creating of dynamic mesh, the attachment picture show the error postion:only the top face of the bowl go up while other required faces keep stationary.
The upper meshes' character: Hex/Wedge cooper size 3
The lower meshes's characer: Tet/Hybird TGrid size 3
I just want to let the upper past being suppressed when the mesh is move while the lower part hold its shape.
Would you please give me a detail depict of operation process if you have a relative experience on this things.
Thank you for advance.
handle your model with layering (if it is not already done)
define the upper surface from red bracket domain as moving wall, and the 2 lower surfaces (one also belongs to green bracket domain) as stationnary.
You also need to define parameters in Meshing option tab for moving and stationnary entities.
Check tutorial 11 - Using Dynamic Meshes
You means to keep the lower part stationary and move the upper part?
Maybe I want to let the lower part go up along the Z axis,so the the 2 surfaces can not be stationary but move up keeping its shape. Do you have any idea?
then define upper surface from red bracket domain as stationnary.
the 2 lower surfaces (one also belongs to green bracket domain) as moving with rigid body.
As I can remember you need also to define the green bracket volume as rigid body.
For that you need to define this domain as separate one (in gambit you can define it as another fluid domain : Specify Continuum Types
PS: moving down the upper surface will give same results: it is just a reference stuff
