# Pre-Analysis & Start-Up – Lesson 2

### Pre-analysis

The equivalent stiffness of the model can be determined:

where
R is the reaction force
$\delta$ is the deflection
L is the length of the model

We will find the reaction force and the support and use the above relation to verify the simulation.

### Start-Up

The following flow chart illustrates the steps to carry out Ansys simulation starting from Micro CT Scan.

Open Ansys Workbench:

We will import the Abaqus input file into External Model and convert it into a Geometry Setup that Ansys can simulate.

Expand Component Systems in the Toolbox. Locate External Model and drag it into Project Schematic:

Right click on Setup > Edit > Location > Browse, and locate the Abaqus input file.

Once the Abaqus file is imported, select the file name just imported (2nd row under the Column Heading "Data Source" ). This will populate the Properties of File in the panel below. There, make sure that the Unit System selected are in mm, as shown below:

Click on the Project Tab to return to Project Schematic. You should see an update symbol  next to Setup. This means the input file has been loaded and External Model is ready to generate a model.F
