Solidworks flow simulation time dependent













This example is a time-dependent thermal analysis study, to understand how quickly this will heat and/or cool.

  • We can now run the study and analyze the results.
  • Convection Coefficient is 100 W/(m^2.K), Bulk Ambient Temperature is 300 Kelvin (K).
  • Accept that, and start a new Convection for the exposed faces of the microchip.
  • Define Bulk Ambient Temperature (the temperature that surrounds the model) as 300 Kelvin (K).
  • Define the Convection Coefficient as 250 W/(m^2.K).
  • Select all the exposed faces of the heat sink.
  • Right-click on Thermal Loads and select Convection.
  • Because the connectors are insulated, we don’t need to define those.
  • We now need to define the convection that is coming off of the rest of the faces on the heat sink.
  • Define the contact based on the conductive glue 2.857e-6 K/W.

  • Click the two faces that touch between the microchip and heat sink.
  • Create a Local Interaction, and make sure it is set to Thermal Resistance.
  • The glue is not physically modeled, we are going to insert it as a contact resistance. Between our microchip and heat sink, we have a thermal conductive glue to help with the dissipation.
  • Next, we need to consider how this heat is going to be dissipated.
  • Use the FeatureManager flyout tree to select the microchip part.
  • Right-click on Thermal Loads, and select Heat Power.

    Then we are going to define the heat power of the microchip.We will start by creating a new Thermal Study.Connectors – Insulated and used to connect to the rest of the electronic components.įor this example, we will be setting it up as a steady-state thermal analysis, which means there is no time factor involved.Our model will consist of a few different parts:
