Guidelines for preceding tutorial

You should perform [Base Model Creation Tutorial] before this tutorial. 
The base model created by this tutorial can be used in  [G-Modeling Tutorial - Rigid ↔ FFlex] as well.
Go to Base Model Creation Tutorial

Step 01 – Meshing

[Steps]

1. To analyze the effect of deflection of Pushrod, it is generated as RFLEX body by following operations
2. Move <Flexible> Tab & Run the <G-Manager>
   
3. Click the <Pushrod> body.
4. In the <G-Manager> dialog, Select the <FFlex> and <Mesh>
5. Click the <Execute> button. You can enter Mesh mode.
6. Click the <Assist Modeling>, and change the Geometry for FDR as shown because the default geometries are not appropriate.
7. Click the <Mesh>, set the option:
• Solid4(Tetra4)
• Max Element Size : 1
• Max Element Size : 0.1
8. Run the Mesh
9. Do Not Exit Mesh Mode, yet.

Step 02 – Run the RFlexGen

[Steps]

1. Click the NodeSet, and makes one NodeSet with two master nodes of FDR (81540, 81541)
2. Exit Mesh Mode
3. Run <G-Manager>
4. Select the Meshed Pushrod
5. Change the target to RFLEX
6. Select <Swap using RFlexGen>
7. Define the Output RFI file path
8. Click the <RFlexGen> button in the middle of dialog
9. Then, RFlexGen dialog will appear. And, select the <Select NodeSet> in the <Interface Nodes> option
10. Click the <N> button, and select the 'SetNode1' in the GUI
11. Click the <Execute> button
12. After the RFI generation is completed, click the <Close> button. It return to G-Manager Dialog.

Step 03 – RFLEX MFBD Modeling

[Steps]

1. In the G-Manager dialog, Click the <Execute> Button. G-Manager will convert the Pushrod body to RFLEX body that is generated in the previous step.
2. Open the properties dialog of Pushrod RFLEX body
3. Using Animation of Mode Shape, confirm the mode shapes of Pushrod RFlex body
4. Run the Simulation then Play the animation and review the animation result

Step 04 – Compare the Results between RIGID & RFLEX

[Steps]

1. Generate Stress/Strain Shape using <Strain/Stress Shape Generation> in the RFlex group.
2. Click the <Contour> Icon.
3. Select the <SMISES(Von-mises Stress)>, and click the <Calculation> button
4. Click the Apply button.
5. Play the Animation. During animation, you can see the max stress and stress contour plot
6. Click the <Plot1> at the model tab, that was already opened plot result of the rigid body model at the 'Step 02'
7. Import the '*.rplt' file of Pushrod RFlex body model
8. Draw the same plot curves (Pos1_Relative and Vel1_Relative of Valve_Trans joint)
9. Compare two plot result between RIGID and RFLEX result.

Tip: If you convert RFLEX Pushrod to FFLEX Pushrod, you can get the same plot result as like STEP9. But, RFLEX solving performance is faster, It’s RFLEX advantage.

Step 05 – Swap RFLEX to New RFLEX

[Steps]

At previous step, confirmed the RFLEX simulation result. However, if the result of Pushrod deflection is not acceptable, user will consider the more stiff Pushrod design to get the more strength. To do that, G-Manager will support user!

1. Run G-Manager, click the Pushrod RFLEX body
   
2. Select the <RFlex> as Target and select <Swap using RFI File>
3. Select the new Pushrod RFLEX RFI file in the Option menu. ('Pushrod_RFLEX_NewDeisgn.rfi')
4. Click the <Execute> button.
5. Pushrod RFLEX body is replaced by new defined RFI file.
6. Run the simulation.
7. Review the Simulation result. You can see the more stiff result of Pushrod RFLEX body. (You can compare the plot results again)

Step 06 – Convert RFLEX to Shell CAD data

[Steps]

For efficient simulation, user may want to convert RFLEX body to RIGID body type. If user does not have original CAD data file of RFLEX body, user can easily convert flexible body to rigid body using “Convert to Rigid Shell” option of G-Manager.

1. Run <G-Modeling>
   
2. Click the RFLEX body
3. Select Target as <Rigid>
4. Select the <Convert to Rigid Shell> option & Check On <Mass & CM Position>
5. Click <Execute> button.
6. Pushrod RFLEX body is converted to Rigid Shell Data
7. Open properties dialog of Pushrod. You can confirm the Rigid body type of Pushrod & Mass/Inertial data
