I am modelling a hydro scheme which features a vertical shaft directly at the intake. So lets says the intake is J1 at elevation 100m and drops to J2 at 50m by a 50 m length of pipe before completing a 90 degree bend to horizontal.
Whe using the profile viewer, the base elevation shows this as a line spaning 100 m to 50 m elevations on the y axis and 50 m on the x axis. Does hammer "Know" this pipe is vertical, or is there some way I must define this, or does it simply not matter for transient analysis as long at I insert a minor loss to account for the 90 degree bend?
Thank you for assistance.
That is being considered as well. Basically information from the Transient Analysis Detailed Report would be available with other results fields that are available in the Transient Results Viewer. There is no direct timeline for when this might be included, but it is something that has been submitted.
Thanks,

Thank you, that answers my question well.
Another (unrelated) feature which would be great to see in future versions is the ability to plot turbine behaviour (speed, gate posn etc) in the same plot as the pressure, it would save a lot of time exporting to excel every time a run is done and gives a much better understanding of what is going on.
HAMMER can model vertical pipes with viable results, though how it will look in the profile will not be accurate. The following steps are basically how you would set up the model..
When entering the data for the vertical pipe length, enter the correct node elevations and the pipe length as a user-defined length. With the correct data entered, the program will correctly calculate the modeling effects as a vertical pipe. It will not be displayed correctly in the profile though.
There is a feature request already submitted about the display of vertical pipes in the profile viewer. A future release of HAMMER will hopefully correctly display the vertical pipe in the profile viewer. The results are accurate if you set up the model similar to the steps above.
Note that if you have a bend in a pipe you will need to model this as a minor loss.
