Solving FSI Applications Using ANSYS Mechanical and ANSYS Fluent

This training course covers the process of performing one-way and twoway FSI in Workbench between Fluent and ANSYS Mechanical.
It is intended for users with some experience using both Fluent and
Mechanical.
Course Objectives:
– Provide an understanding of the Workbench user interface, as related to FSI workflows
– Learn the procedures for performing one and two-way structural FSI analyses,including steady state and transient, using co-simulation with System Coupling
– Learn the procedures for performing various one-way FSI analyses, including thermal and structural, steady state and transient, for a variety of different load types

Overview of FSI in Workbench

Co-simulation Overview, Geometry and Meshing

This lecture starts by describing how the co-simulation coupling
process works. The main capabilities of System Coupling are then
discussed along with the current limitations.

Co-simulation Setup

This section will cover the Mechanical setup in the context of a System
Coupling co-simulation. We’ll discuss Analysis Settings, creating Fluid
Solid Interfaces and other topics relevant to System Coupling
simulations.

Fluent Setup
The Fluent setup for System Coupling simulations will be covered next.
In addition to describing how to label Fluent boundaries to
send/receive data from MAPDL, we’ll discuss creating useful monitor
data, solution output, solver controls and other general considerations.
System Coupling Setup
Here we’ll cover the settings in the System Coupling GUI, including
Coupling Steps & Iterations, creating Data Transfers between
participant solvers and solution output controls.

Moving and Deforming Meshes for System Coupling

Smoothing Methods
This section discusses the three mesh smoothing methods available in
Fluent; spring, diffusion and linearly elastic solid smoothing
Remeshing Methods
Here we’ll provide a brief overview of each remeshing method. These
are Local Cell, Local Face, Zone, Region Face, and 2.5D remeshing
Layering
This section discusses the Layering method in Fluent
System Coupling with MDM
In this section we discuss several points to consider when using System
Coupling with MDM

Co-simulation Solution Process and Post-processing

Co-simulation Convergence

This lecture focuses on converging System Coupling simulations.
There are many controls that can impact convergence, so we’ll start
by identifying the controls available.
Obtaining good convergence requires a methodical workflow. We’ll
discuss:
• Using separate fluid and Mechanical simulations to first identify
any non-FSI problems
• Correct initialization for FSI cases
• Monitoring convergence
• Convergence controls and their effect
• Identifying unstable FSI case and how to stabilize the solution
• General convergence advice and debug tools
