I noticed that the `catalyst_execute` returns a `catalyst_status_ok` even if a pipeline execute fails.  
Is there any plan in future, to return an error code when `ExecutePipelines` fails ?

I was thinking of returning a `false` if the `ExecutePipelines` fails and catch it in `catalyst_execute_paraview`.

it makes sense for me too to return an error if the pipeline failed, AFAIK there is no plan to improve that so feel free to change that if you can 🙂

I agree that it make sense to handle `vtkInSituInitializationHelper::ExecutePipelines(params)` return value in `catalyst_execute()`.
