You can find all relevant data for this tutorial in the Example folder! ("C:\Program Files\MSC.Software\MSC Apex Generative Design\2019\Examples")
Step 1: Create a new project
In a first step, you need to create a new project. All data (geometry and configuration) directly will be copied and saved in a new project-folder, located in your workspace:
- Start AMendateStart MSC Apex Generative Design 2019
- Create a new project using the symbol
- Enter a projectname project name and save the project
- Open the newly created project
...
- Upload all relevant stl files by clicking on the symbol in the objects/surfaces area
- select all stl files
- The field at the bottom shows notifications and makes you aware of missing input
- The uploaded objects are listed in the objects/surfaces area.
- Assign a Material to each object/surface and enter the specific values for the Young's Modulus Modulus (210e3) and poisson ratio(0.28) in the Material Editor.
- Activate the option design space for the relevant stl file. Only one volume can be selected as such.
- In this case: Hook - design-1
Step 3: Definition of boundary conditions
Go to the boundary conditions tab to enter the loads and fixations as follows
- Kraft1 Force: Object "auflage1" experiences a force of -20000 N in y-direction.
...
. For each boundary condition a name, a space and the specification of the boundary condition is entered as follows:
| Name | Object | Direction | Value in N |
|---|---|---|---|
| Force | Hookinterface1 | y | -20000 |
| Name | Object | Direction |
|---|---|---|
| Fixation1 | Hookborehole1 | x, y, z (=0) |
| Fixation2 | Hookinterface1 | z (=0) |
- A total of 1 force and 2 fixations should have been created as a result.
All boundary conditions are must be assigned to the load cases. The number of load cases can be changed using the "+" or "-" characters. The assignment of the boundaries to the load cases can be made in the boundary conditions or load cases area.
- Active in load case 1: Kraft 1, Lager1 and Lager2Loadcase1: Force, Fixation1 and Fixation2
Step 4: Definition of optimization parameters
...
- Choose the design type normal.
- Enter the optimization goal stress: 260 MPa
- Open Result File Formats. The following result files should be activated:
- stl File: results of each iteration in stl file format
- stl Files Intersected: result of each iteration intersected with the design space in stl file format
- ply Files with Stress: results with the information of stresses of each iteration (must be activated to show the results in the Visualization space)
- ply Files with Displacement: results with the information of displacements of each iteration (must be activated to show the results in the Visualization space)
- More information on result file formats here
All Inputs can be viewed and checked in the configuration file. The file should look like this.
...
If all data are correct, the optimzation optimization can be started and tracked in the results area.
...
The optimization is finished after 64 iterations (optimizationtype: optimizing).
Step 7: Visualization of Stresses
The legend can be influenced using the slider. The function "Automatically set to local minimum and maximum" considers the stresses of each iteration and sets the values from the current iteration.
Step 8: Visualization of Displacements
The legend can be influenced using the slider. The function "Automatically set to local minimum and maximum" considers the displacements of each iteration and sets the values from the current iteration.
