Boundary conditions > Associating boundary conditions with a solution

Manage solution associations

  1. In the Simulation Navigator, right-click the simulation node and choose Solution Manager.Note: The Solution Association Manager is available only for solutions that do not use steps to manage boundary conditions, such as Simcenter 3D Thermal or Simcenter 3D Flow.

  2. In the Solution Association Manager dialog box, from the Type list, select the boundary condition type, such as:LoadsConstraintsSimulation ObjectsThe types of boundary conditions available depend on the solver and solution type. Only boundary condition types that may be stored in solutions for this solver and solution type are listed.

  3. (Optional) Filter the listed boundary conditions. In the Filter group, from the Select Type list, choose from:All shows all boundary conditions of the specified type that are appropriate for the selected solution.Folders shows only boundary conditions folders. Selecting a folder for a solution will associate all boundary conditions in the folder with the corresponding solution.Specified boundary conditions. Choose from a list available boundary conditions for the current solution. For example, if you have selected a linear statics solution and specified Constraints as the type, you can choose from constraints such as User-Defined, Fixed, and so on.You can type a string in the Specify Wildcard field to filter available boundary conditions by name.Click the Filter button to apply the filter and update the table.

  4. (Optional) You can click Switch Rows and Columns to alternate between listing boundary condition for each solution and listing solutions for each boundary condition.

  5. Click cells within the table to add or remove boundary conditions from any listed solution. Right-click a cell to quickly add or remove a specified boundary condition for all solutions, or to add or remove all boundary conditions for a specified solution.

  6. Click OK to accept all changes and close the dialog box.
