I am trying to do transient analysis for water containing tankers using ANSYS APDL but i don't exactly know how to assign contact between fluid and structural shell so it can account fluid structure interaction. any recommendation on steps how to do it is appreciated.
thanks
Hydrostatic elements for fluid modeling (3D HSFLD242 and 2D HSFLD241) were introduced in older versions of ANSYS. They are designed to simulate a closed volume of a liquid medium bounded by shell elements. They make it possible to take into account the presence of a liquid of a certain mass, as well as the change or invariability of its volume during the deformation of the vessel in linear and nonlinear static and dynamic calculations.
In the presence of a free surface, the effects of liquid splashing must be simulated either using elements of the FLUID series, or by linking the strength calculation with the problem of computational fluid dynamics.
Hydrostatic elements are implemented as surface elements that cover
a closed body cavity wetted with a liquid. Such
elements can be created with the ESURF command. Hydrostatic elements are not explicitly supported in the Workbench Mechanical interface, we add them to the model using APDL commands.
Dear Andrii,
Thank you so much for your response. I was trying to do transient analysis for structure model with TLD using APDL but i can't figure out how to couple the sloshing force of the liquid with the structural deformation (response). Can assigning those FLUID element series in workbench solve the problem?
