WebThe surface-based fluid cavity capability can be used to model a liquid or gas-filled structure. It supersedes the element-based hydrostatic fluid cavity capability (see “Modeling fluid-filled cavities,” Section 11.5.1) in … WebAn additional volume can be specified for a fluid cavity in Abaqus/Explicit. The additional volume will be added to the actual volume when the boundary of the cavity is defined by a specified surface. If you do not specify a surface forming the boundary of the fluid cavity, the fluid cavity is assumed to have a fixed volume that is equal to the ...
