  - Ohmic Heating: Domestic Fuse
    This tutorial demonstrates some of the capabilities of the Ohmic Heating model available in Simcenter STAR-CCM+.
    - Prerequisites
      The instructions in the Ohmic Heating: Domestic Fuse tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Surface Mesh and Naming the Simulation
      A CAD file containing the fuse assembly has been prepared for this analysis.
    - Examining the Imported Geometry
      The imported CAD parts, which represent the different parts of the fuse and its holder, are contained in the Geometry > Parts manager node.
    - Increasing the Tessellation Density of the Fuse Wire
      To ensure that the thin fuse wire has a well-defined surface, increase the tessellation density of the imported surface to represent the surface with a higher density of triangles.
    - Assigning Geometry Parts to Regions
      Assign geometry parts to regions before surface or volume meshing takes place. Simcenter STAR-CCM+ allows you to create regions and boundaries that are based on the parts and their surfaces.
    - Setting up the Mesh
      Use the surface remesher with the polyhedral mesher to create the volume mesh.
    - Adding a Volumetric Control
      Add a volumetric control to provide adequate resolution of the volume mesh within the wire. When adding volumetric controls, it is first necessary to create the volume shape within which custom mesh control applies, and thereafter to select this shape within a volumetric control itself.
    - Generating the Mesh
      You can now create the volume mesh for the simulation.
    - Specifying Physics Models and Material Properties
      You can now specify the physical models and the material properties for this simulation.
    - Assigning Physics Continua
      For a multi-region simulation, you must assign a physics continuum to each region. Through this assignment, the different physical models and material properties are assigned to the respective region.
    - Setting Global Initial Conditions
      Specify the initial electrical potential value for the Copper (Ohmic Heating) model.
    - Defining Boundary Conditions
      Set the boundary conditions for the Ceramic, Clip+ve, and Clip-ve regions.
    - Setting up Reports, Monitors, and Plots
      By default Simcenter STAR-CCM+ produces a residuals plot which can be used to monitor the convergence of the solution. It is useful to create more monitors to help in assessing convergence.
    - Setting up a Plane Section
      You can use a plane section to visualize the temperature within the parts.
    - Setting Up a Scalar Scene
      To display the electric potential for the two clip regions and the temperature for the fuse cross-section derived part, you create a single scalar scene.
    - Setting Solver Parameters
      You change the solver settings to help the solution converge quickly and maintain stability.
    - Setting Stopping Criteria
      You now specify for how long the simulation runs.
    - Running the Simulation
      The simulation is now ready to be run.
