FSI analysis using Abaqus and StarCCM+ using co simulation and mesh morphing technique
1. Create the Solid model and extract the fluid
volume out of it in CAD
2.
Setup and Run the Static analysis in Abaqus
using normal methods in the Solid CAD model.
3.
Set up the CFD study in StarCCM+. Make sure that
you have created a separate boundary for all the mating surfaces between solid
and fluid CAD models in StarCCM+.
Import Abaqus data into StarCCM+
1.
Extract and create input file (*.inp) file in Abaqus
CAE model.
2.
In StarCCM+ window, File – Import – Import CAE
model
3.
Locate the Abaqus input (*.inp) file and click
OK.
4.
In
Simulation tree of StarCCM+, Inside Imported Models, and Locate Abaqus data.
5.
Right click in the Abaqus imported model and
Select Import CAE Solution Data
6.
Locate Abaqus result file (*.ODB) and open it.
After importing the Abaqus ODB file to StarCCM+
1.
Map the surface displacements from Imported
model to StarCCM+
2.
Check whether the data is properly imported in
Data mappers
3.
In a scalar scene – select the scalar field as
“Mapped vertex imported displacement
4.
To activate mesh morphing the solver should be
in unsteady – Select Implicit unsteady in physics model
5.
Activate Mesh morphing in Tools - Motions
6.
Select
Morpher from Physics condition of Wall and choose displacement in method
Select Morpher: Linear Displacement
method as field function from physics values
7.
Select the Field function vector function as
Mapped vertex imported displacement
8.
Step the unsteady run for one iteration after
freezing the segregated flow and K-epsilon turbulence solvers
9.
Step the solution
10.
Plot the Morpher Displacement in a scalar scene
and verify the deformations are properly morphed
11.
Revert back to Steady Simulation
12.
Unfreeze the solvers
13.
Run the solution
