Attach a load recipe to a solution
You can attach a load recipe to a solution only if the solution uses a supported solver, analysis type, and solution type. For example, you could attach a FEM load recipe to a Simcenter Nastran solution that uses a structural analysis. You could attach a mode set load recipe to a Simcenter 3D Noise and Vibration solution that uses a vibro-acoustic analysis and a modal acoustic transfer vector (MATV) response solution type.
In the Simulation Navigator, make sure the solution you want to add the load recipe to is active.
Expand the Load Recipe Container node, right-click a load recipe node, and choose Attach to Active Solution.
If a load recipe is already attached to the active solution, and you want to replace it, click Yes when prompted.The original load recipe is replaced, all the subcases associated with that load recipe are deleted, and new subcases with the appropriate loads are created based on the new load recipe.
In the Attach Load Recipe to Solution dialog box, from the Subcase Type list, select the type of subcase to create using the load recipe.Note: If the software determines the subcase type based on the solver, analysis type, solution type, and load recipe configuration, the appropriate subcase type is selected automatically, and you cannot change it.
From the Load or Boundary Condition Type list, select how to handle the loads:Separated—The load recipe creates a separate load for each node, which can create a large number of objects in the Simulation Navigator. You can edit separated loads after they are created.Aggregated—The load recipe creates a single load for each load type, such as force, pressure, enforced velocity, and so on. Aggregating loads can significantly reduce the time it takes to create the solution and to display the loads in the Simulation Navigator. However, you cannot edit aggregated loads after they are created.File Reference—The load recipe creates a single load for each load type. In this case, the solver reads the data directly from the data source file, which can further improve performance. However, you cannot modify any of the data from the data source when you create the load recipe, and you cannot edit file reference loads after they are created.The available options vary, depending on the load recipe target type and other considerations. For more information, see Separated, aggregated, and file reference loads.
Click OK.If errors or warnings are detected during the validation process, the Information window provides details. For more information, see Load recipe validation.
