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 AMendate.
- Create a new project .using the symbol
- Enter a projectname and save the project.
- Open the newly created project.
Step 2: Model generation
- 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 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 and poisson ratio in the Material Editor.
- Activate the option design space for the relevant stl file. Only one volume can be selected as such.
Step 3: Definition of boundary conditions
Go to the boundary conditions tab to enter the loads and fixations as follows. For each boundary condition a name, a space and the specification of the boundary condition is entered as follows:
| Name |
|---|
- Kraft Force: Object "fussFlaeche1" experiences a force of -1000 N in y-direction.
...
| Object | Direction | Value in N | |
|---|---|---|---|
| Force | Pedalfootsurface1 | y | -1000 |
| Name | Object | Direction |
|---|---|---|
| Fixation | Pedalaxle1 | x, y, z (=0) |
...
- A total of 1 force and 1 fixation should have been created as a result
- The object "Pedalfixation1" does not experience any force or fixation but is necessary to connect the pedal with the axle. Therfore the form is considered in the optimization.
All boundary conditions are 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: dis1, dis2, dis3, dis4, conditions4L and conditions4RLoadcase1: Force and Fixation
Step 4: Definition of optimization parameters
...
- Choose the design type normal.
- Enter the optimization goal stress: 60 MPa
- Set the symmetry setting: Z-Axis
All Inputs can be viewed and checked in the configuration file. The file should look like this.
...
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 stressesof 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.
