Solidworks Flow Simulation 2012 Tutorial.pdf __link__ May 2026
The SolidWorks Flow Simulation 2012 tutorial, a 140-page guide, offers essential steps for resolving simulation failures, including using the Check Geometry tool, applying lids to openings, and refining mesh levels [1]. Following these procedures helped fix a stalling high-efficiency cooling duct design by enabling proper mesh convergence and boundary condition definition [1]. For a guided walkthrough, refer to the PDF documentation.
Step 9 – Validation (Compare with Theory)
- Pressure drop from simulation vs. Darcy-Weisbach equation.
- Drag coefficient vs. published experimental data.
- Heat transfer coefficient vs. Dittus-Boelter correlation.
Key Concepts Covered:
- The Flow Simulation Tree: Unlike standard SOLIDWORKS features, Flow Simulation adds a specific study tree to the Feature Manager.
- Toolbars: Introduction to the Flow Simulation toolbar, including the Wizard, Calculation Control, and Results tools.
- Add-ins: How to activate the Flow Simulation add-in within SOLIDWORKS.
4. Installation & Interface overview
- Installing Flow Simulation 2012 (components, license note)
- Starting Flow Simulation from SolidWorks, menu locations, ProjectManager tree
- Key panels: General settings, Boundary Conditions, Goals, Mesh/Automatic mesh
Step 5 – Meshing (Crucial for Accuracy)
The 2012 tutorial uses adaptive meshing – it refines cells automatically where gradients are high. solidworks flow simulation 2012 tutorial.pdf
- Initial Mesh Level: 3–5 (coarse to fine). Start with 3 for fast testing.
- Refinement Criteria: Velocity or temperature gradient > 20%.
- Manual Refinement: Add local mesh control at narrow gaps (e.g., valve seat).
- Check Aspect Ratio: Avoid cells with ratio > 100.
Step 3: Define Boundary Conditions
- Click Flow Simulation > Insert > Boundary Condition.
- Inlet:
- Select the face of the lid at the inlet.
- Type: Inlet Volume Flow Rate.
- Value: Enter a value (e.g.,
0.01 m^3/s). - Click OK.
- Outlet:
- Select the face of the lid at the outlet.
- Type: Pressure Outlet.
- Value: Usually set to environmental pressure (101325 Pa).
- Click OK.
Step 7 – Results Visualization
- Cut Plots: 2D slice showing velocity magnitude (color map) + vectors.
- Surface Plots: Pressure distribution on valve walls.
- Flow Trajectories (streamlines): Show recirculation zones.
- Isosurfaces: Constant velocity or temperature surfaces (e.g., 0.5 m/s wake).
2. Conjugate Heat Transfer (The Electronics Cooling Example)
Perhaps the most practical section for mechanical engineers. The 2012 PDF uses a simple PCB with heat sinks. The SolidWorks Flow Simulation 2012 tutorial, a 140-page
- Lesson: Applying thermal power to solid bodies.
- Lesson: Creating a Computational Domain.
- Lesson: Using Surface Goals to monitor maximum temperature on a chip.
- Result: Visualizing cut plots for temperature gradients (red/yellow/blue spectrums).
Porous Media
- Input: Permeability (m²) and inertial resistance (1/m).
- Example: Flow through a honeycomb or sintered metal.
- Pressure drop ~ velocity².
