How To Use Your Settings in Reliability Workbench (FaultTree+)

We have collected commonly asked questions by our 1000’s of users. Some of the questions that we’ll answer along the way include:
Why do my cut sets show gate names with an asterisk next to them?
OK, so I enter a “failure rate.” Is that failures per… hour? Year? Geological epoch? What are the units?
This fault tree takes ages to calculate. Can I speed it up?
Fault tree uses approximation methods for solving the tree? Do I have any control over that?
My computer crashed and I lost 3 hours of work! Can I create automatic backups of my project?
What if I want to see MTTF on my fault tree, instead of Q?
I have a plotter. How do I print the whole tree on one piece of paper?
Can I force scientific notation in the results?
What if I don’t want to delete the inputs to a gate when I delete the gate?
I really love the font Comic Sans. Can I use that in my fault tree?
Also, chartreuse is my favorite color. How do I set that as default?
How do I set default options, so I don’t have to reset these every time I start a new project?

We’ll also look at the useful and often-overlooked Report Options. Did you know that you can force the diagram to be black & white for printouts? Or make the fault tree symbols bigger? Or change the order of the pages?

What is a LOPA and how can one use ETA to address it?

If you are looking for LOPA information chances are you probably already know what a LOPA is. For any of you are not familiar with a LOPA study, it could mean any number of things. However, for us a LOPA is an acronym meaning: Layer Of Protection Analysis. A LOPA can be a good and logical beginning, or addition, to your PHA (Probabilistic Hazard Analysis) studies. Which leads us to our next acronym ETA (Event Tree Analysis). Event tree analysis diagrams can be an effective approach to tackling your LOPA studies. Since this is probably easier viewed than described please take the time to watch our webinar addressing this topic:
