I’m interested in testing tibia designs with stem in the knee app. I also want to add a different component as the meniscus between the femur and tibia. I'm not too bothered about the contact mechanics. Instead, I'm only interested in the tibia designs. The documentation uses the screenshot below as the tibia component, which I would use as the meniscus.

I have hit the following problems:

1. Error after editing dwell points and surface of the "tibia" (my meniscus) as shown in the following screenshot. I can go into Analyst mode and fix this in the normal CAE but it wouldn’t be recognised in the test suite.

   
2. Nowhere to specify a tibia component with a stem into the tibia bone. Again, I can change to analyst mode and use the normal CAE mode to import and assemble. But the testing suite would not recognise that and then it’s the same as simulating without the app. Is it possible at all?
3. I’m only interested in two workflows: the TF constraint and basic TKR loading. But I can’t really progress until points 1-2 are resolved.
