Constant cavity volume
Constant cavity volume
(OP)
Dear all,
I am trying to simulate cardiac contraction for a left ventricle. I want have to keep the cavity volume constant for my simulation.
I have read alot of documentations for tyre simulation in abaqus where they give a constant volume for internal air part but no success to find inp example to understand how you can give such boundary conditions.
Anyone can give me some hints where can I find such info?
Any help is very welcomed,

I am going to check it out! for now I had a look on the boundary condition fluid cavity to see if I can consider a fluid inside without adding a new mesh.

I have a complicated mesh(hexahedron). For now, I am trying to figure how I can close my surface directly in abaqus.

RE: Constant cavity volume
The phase I am trying to simulate is called isovolumic contraction, means the moment where the valves are closed and the muscle contraction starts to a certain stress. When the pressure inside the ventricle reaches to about 10kPa valves open and contraction continues more strong to reach 16kPa.
Thats what I am trying to do but I cant close my mesh while it was empty (the cavity) from beginning.
