Coupled Fluid / Structure Interaction Simulation Using Abaqus CEL
For a system which involves a fluid medium contained inside a deformable structure, such as a fuel tank system, a simulation which couples the structure and fluid may be required depending on the system performance metric of interest. Simulation methods for fluid / structure interaction (FSI) have been gradually developed by CAE engineers since the advent of increased computing power. A limitation in using previous FSI simulations is the dynamic event time period that the FSI method can simulate. With the new CEL function, Abaqus can simulate a coupled fluid / structure dynamic event of several seconds real-time duration in days instead of weeks as compared to other available software. Abaqus/Standard and Abaqus/Explicit CEL function can be used to create a seamless fuel tank system simulation method to assess the fuel tank assembly and road loading performance.

Drag and Buoyancy Effects
Hello,
I am currently using the CEL approach in Abaqus to study fluid-structure interaction.
I am relatively new to the concept and a couple of areas I am not too clear on is whether drag forces and buoyancy can be captured using CEL.
If they cannot be accounted for directly in the model, is there a possible work-around that could simulate those effects?
Thank you very much.
