Why does a generated study contain outcomes with errors?

In some cases, a study with the correct setup may generate outcomes that contain errors.

Possible solutions

• Consider using a starting shape to improve outcomes.

  • In some models, using a starting shape may reduce the model’s initial shape. Starting with the smaller initial shape, a generation process can proceed further within the iteration limit.
  • If you have an outcome with the Completed status, but you want to use it, you may use it as a starting shape and generate again.
  • If the obstacle geometry in your model is large, using a starting shape may prevent the initial shape from dividing during the outcome generation.

• Review the obstacle geometry in your model.

  If it is too large, it may result in dividing the initial shape into two or more parts during the outcome generation.

  To avoid it, modify the generative study setup. For example, redefine the obstacle geometry, and then generate outcomes.

• Review the preserve geometry in your model.

  If one of the following issues occurs, it may cause the outcome geometry to separate into regions during the generation:

  • The preserve geometry bodies where you applied loads are too small compared to the model size.
  • The preserve geometry bodies differ in size significantly.

  To avoid the separation, try increasing the load magnitudes or reducing the difference in size between the preserve geometry bodies.

• Modify the Outcomes Resolution setting.

  Each model is unique. You need to find an optimal setting for your model. The default setting doesn't work best for every model.

• Apply loads reflecting a real-world situation.

  Example:

  Your model has two preserve geometries. You apply a load of 1 N to one of them and a load of 10,000 N to the other.

  In this example, the solver may encounter numerical issues and exclude the smaller load from the outcome generation.

• If you select the Milling manufacturing method in your study, review the Milling settings.

  Verify that your tool sizes are appropriate for your milling operation. Adjust all parameters of the tool to the study setup so that the tool can remove material without affecting the preserve geometry. Sometimes, using a lower Outcomes Resolution setting may help.

• If you select the 2-Axis Cutting manufacturing method in your study, consider using a lower Outcomes Resolution setting.
