What do the different colored lines in a transient results viewer profile represent?
When I create a graph under View > Graphs, this seems to only show the initial conditions. Where can I view detailed graphical results of the transient simulation?
Why do I get a negative pressure at a high point in my system? Shouldn't the pump add enough head to push the water over the hill?
When importing a DXF as a background, it does not show up in the model, even when pressing zoom extents.
