For the force input the Clearance Region Tool is used with an offset of 3 mm to ensure that there is enough space around it. Only the faces around the middle of it are chosen, because the rest is already covered with the access regions. The force input is a Retained Volume in this optimisation. It should always be connected to the Design Space via Non-Design Spaces (including Machining Allowances).

To create the Access Region the Access Region Tool is used again - only this time the “cross section” method
...
In this case four forces and one moment are defined. The first two are applied on the retained volume and the last three on the Non-Design Space that is connected to the sensor:
Name | Force/Moment/Pressure/Gravity | Direction | Value in N; Nmm |
|---|---|---|---|
Force - Moment 1 | Force on Retained Volume | Fy; Fz | -1000; 1000 |
Force - Moment 2 | Force on Retained Volume | Fx; Fy; Fz | 600; -800; -200 |
Force - Moment 3 | Force on Non-Design Space | Fy | -500 |
Force - Moment 4 | Force on Non-Design Space | Fx; Fy; Fz | 150; -200; -100 |
Force - Moment 5 | Moment on Non-Design Space | Mz | -2000 |
...
Three constraints are created and attached on the Non-Design Spaces on the lower side:
Name | Direction |
|---|---|
Constraint 1 | x, y, z (=0) |
Constraint 2 | x, y, z (=0) |
Constraint 3 | x, y, z (=0) |

You can always change the Strut Density, Stress Goal and Complexityto influence the results and try out different options
The Complexitycan be increased for a higher resolution and more detailed result (increased calculation time!)
The Strut Densityinfluences the structures which are formed during optimisation
