Bookshelf Jet Engine Bracket Tutorial
Step 1: Transfer Design Candidate & Map LBCs and Material
For this Tutorial the Bookshelf Jet Engine Bracket project is used.
For a Retransition to a NURBS-Geometry a non-intersected optimisation result is needed. Therefore, the Smooth-Geometry from the Post Processing can be used. Go to the options of the “Transfer Design Candidate to pre processing” Button and activate the option “Map LBCs and Material”. Then press the button to start the process.
...
The success of the transition and the mapping of LBCs and the Loads & Boundary Conditions (LBCs) can be checked in the Map LBC tab. All newly created LBCs their status are listed and the status for each of them. If an a LBC was not created successfully, the LBC can be manually adjusted by double clicking on the LBC.
...
With the green checkmark the mapping can be confirmed:
...
Save the project and close MSC Apex Generative Design.
...
Open the MSC Apex Generative Design database with the transitioned Design Candidate in MSC Apex.
...
The whole project will be converted to a MSC Apex project. A copy for MSC Apex Generative Design will be automatically created.
...
The geometry as well as the LBCs and Material information are transferred and available for the verification. The Loads are transferred to Remote Loads.
Only the meshing needs to be done as the model preparation. Here is an exemplary mesh for the Bookshelf:
...
The model is set in the Analysis Scene (Analysis Readiness Check) and a Scenario can be created.
...
The Scenario is updated to represent the optimisation. It
Step 3: Meshing
The optimised geometry needs to be meshed with a tetraeder mesh for the reanalysis. For the Jet Engine Bracket a quadratic element with a mesh size of 3 mm is chosen.
...
Step 4: Assign 3D Element Properties
For the reanalysis in MSC Apex a 3D Element Property needs to be created. The corresponding Material ID with the used material (in this case: Titanium) needs to be selected.
If anisotropic material was used in the optimisation a material coordinate system needs to be selected. In this case, create a new / correct one for your anisotropic material orientation.
...
Assign the 3D Element Property to your mesh (not to the solid):
...
Step 5: Set up the static scenario
In the studies tab the static analysis scenario can be set up. Therefore, the model representation need to be linked to the optimised geometry. Under Loads & Constraints the Events can be set up.
...
The scenario can also be expanded to include loads and functionalities unavailable in MSC Apex Generative Design to verify the Design regarding these conditions.
...
Start the analysis and verify the results!
