When a study set up has pre-check warnings or errors, and you run it anyway, the results you obtain may contain errors. The results that are calculated are only as meaningful as the inputs you provide.
Depending on the errors and warnings that are provided in the pre-check, some studies can still be run. The results generated, however, might be difficult to interpret, incorrect, or simply non-existent. Where results are returned, if they make little sense to you, you may want to consider modifying the model, or editing the study set up parameters.
When the solver cannot calculate and return results, these studies are marked as solved with errors in the results.
Once you have made changes, the study can be solved again.
