I have a problem with my reducers and hopefully somebody will help me out.
Everthing works fine when it's generic but when i change the reducer to the actual one it is inverted and it only happens when the pipe goes from small to big.
If the geometry is derived by formulas then there needs to be a test to determine which end is the big end and if necessary swap the values of diameter 1 and diameter 2.
If its done by lookup table then you need to include options for big end x small end and small end x big end.
