Because the case supports a large number of parameter combinations, several different design approaches were necessary to ensure that the model generates reliably across as many configurations as possible. Should you encounter any issues with a specific parameter combination, please leave a comment with the settings you used. I will do my best to reproduce and fix the problem.   See also my other cases:
