Two important results arise from the use of linear elements: 1) weld lines will always be seen on the edge of an element, and 2) air traps
must surround a single node.
The troop now triggers air traps
, so that means they can be in range of mine hazards from above.
Because the city sits in a valley, it's prone to a meteorological phenomenon called an air inversion, where a lid of warm air traps
cold air and harmful pollution close to the ground.
This 'preventative analysis' detects a wide range of potential manufacturing issues such as warpage, weld lines, air traps
, filling issues and hot spots, while determining the optimum gating position.
Moreover, the produced panels will e aesthetically excellent and ompletely free of air traps
, he added.
Filling a long-unmet need for viable programs to simulate gas flows in thick tubular products, CGI says, the new 3D flow analysis programs enable accurate predictions of material weights and time cycles; more precise simulation of wall thicknesses for assessing product strengths and weaknesses; optimization of materials, plastic feed, and gas injection positions; study of variations related to gas timing; and prediction of blowout situations, weld lines, and air traps
The Willamette Valley is caught in a weather inversion, where warm, dry air traps
the cool air below it in a stagnant pocket.
A thin deep rib running the width of a casting can exhibit multiple air traps
. These may be eliminated with a series of ejector pins and/or screw vents, which may not be practical for other reasons.
You may need to change the gate location to avoid race-tracking or air traps
