How Do You Do a Thermal Simulation in SolidWorks?

by

Thermal simulation is a crucial aspect of engineering design, allowing engineers to analyze and optimize the thermal performance of their products. SolidWorks, a leading 3D CAD software, provides powerful tools to perform thermal simulations. In this tutorial, we will explore how to do a thermal simulation in SolidWorks step-by-step.

Step 1: Set up the Geometry

Before starting the thermal simulation, it is essential to have a well-defined geometry of the model you want to analyze. This can be done by creating or importing a 3D model into SolidWorks.

Step 2: Define Material Properties

To accurately simulate thermal behavior, we need to assign appropriate material properties. In SolidWorks, you can define material properties by right-clicking on the part and selecting “Edit Material.” This opens up the Material dialog box where you can specify properties like thermal conductivity, specific heat, and density.

Step 3: Apply Boundary Conditions

In order to simulate realistic thermal behavior, it is crucial to apply appropriate boundary conditions. These conditions define how heat is transferred into or out of the model. SolidWorks provides various boundary condition types such as convection, radiation, and fixed temperature.

Applying Convection Boundary Condition

To apply convection boundary conditions:

  1. Select the face(s) where convection occurs.
  2. Go to “Insert” > “Boundary Condition” > “Convection.”
  3. In the PropertyManager dialog box, specify the convection coefficient and ambient temperature.

Applying Radiation Boundary Condition

To apply radiation boundary conditions:

  1. Select the face(s) where radiation occurs.
  2. Go to “Insert” > “Boundary Condition” > “Radiation.”
  3. In the PropertyManager dialog box, specify the emissivity and ambient temperature.

Applying Fixed Temperature Boundary Condition

To apply a fixed temperature boundary condition:

  1. Select the face(s) where the temperature is known.
  2. Go to “Insert” > “Boundary Condition” > “Fixed Temperature.”
  3. In the PropertyManager dialog box, specify the desired temperature value.

Step 4: Specify Meshing Parameters

A well-defined mesh is essential for accurate thermal simulations. In SolidWorks, you can control meshing parameters such as element size and element type.

To access meshing options:

  1. Right-click on the part or assembly and select “Edit Simulation Mesh. “
  2. In the Simulation Mesh dialog box, specify the desired settings for element size, element type, and other options.

Step 5: Run Thermal Simulation

Once you have set up your geometry, material properties, boundary conditions, and meshing parameters, you are ready to run the thermal simulation. To run a thermal simulation in SolidWorks:

  1. Go to “Simulation” tab > “New Study” > “Thermal.”
  2. In the PropertyManager dialog box, specify a study name and select appropriate options like steady-state or transient analysis.
  3. Click on “Run” to start the simulation process.

Step 6: Analyze Results

Once the simulation is complete, SolidWorks provides various tools to analyze and visualize the results. You can plot temperature distributions, heat fluxes, and perform other post-processing operations to gain insights into the thermal behavior of your model.

In conclusion, SolidWorks offers a comprehensive set of tools for performing thermal simulations. By following these steps and utilizing the various boundary conditions and meshing options available, engineers can accurately analyze and optimize the thermal performance of their designs.
