Specifying a custom weld line angle allows you to see the effect of the meeting angle on the length and severity of the weld line.
The Weld Lines custom plot is available for Midplane and Dual Domain studies. It allows you to specify the angle at which the flow fronts meet and create a weld line.
You can create several plots with different meeting angles to compare the effects. Click the check box next to each plot name to display each plot in turn and compare the effects of the meeting angle.
