Question:

My RAOs look weird, what do I do?

Answer:

Before you do anything else: check the geometry file. The majority of issues are usually related to bad geometry. Look for things like out-of-order stations, incorrect deductions, erroneous geometric features such as poorly fitted components, odd intersections, etc. Also look for hydrodynamically insignificant features that may cause meshing issues. A good first step is to run MC FIXUP. This command will likely fix most (if not all) of these issues if they are found by the program.

If a thorough inspection of the geometry yields no solution, check the following:
