All parts are cut from 3mm / 1/8" Mild Steel Plate.

Give the RAR file + BOM to your favorite laser cutting company to quote then. The reason for this is to avoid selecting part of your model that maybe closed or shut off. CNC Plasma Table: PLEASE NOTE: I do NOT supply kits for these. For “To:” using a small negative number such as -.00001 is suggested. Choosing a negative number with a large magnitude for the “From:” input insures that no negative velocity slips under the radar. You can then select your range of velocities.
Using Velocity Inlet or Outlet would work for this model. When using Pipe Output you are then able to further specify what properties you want to create your selection based on. The tool allows for many other selection types, but in this blog we will focus on Pipe Output Properties. Select Special is a powerful tool available in the edit menu or by using the function key shortcut F6. What is the easiest way to fix this? You could compare your results, remember or make a table of what pipes have negative flow, and manually change the direction of each of these pipes, or you could use select special and change all of the pipes at once. In the below AFT Arrow model it might be hard to determine what way the flow convention is in some of the loops.Īfter running this model there are cautions stating that flow is negative through junctions that may have loss factors that are dependent upon direction. Often times when building larger network models, you may not be sure what the direction of the flow will be and running the model is the only way to determine the flow direction.
