Welcome to part four of our blog series where we share eight quick tips for getting started in Altair Inspire Cast . In parts one, two, and three we solved common meshing issues involving sleeves , vents , and internal voids . In this blog, we’re discussing how to choose the right size element for your simulation.
This is a common question that comes up when running simulations in Altair Inspire Cast, and the answer is...well, it really just depends.
There is, however, one rule that applies when trying to size your elements. There should be at least three elements through the thickness of the thinnest area of your casting.
So how do you find out where the thinnest section of your casting is? There are a few places to look: nominal walls, curved edges, but most commonly, at the gate.
In this example, we can use the measure tool from the ribbon and use the “Measure Length” option to measure for the thinnest area.
In this example, we can see that the gate is 1.5 mm thick so our mesh size should be 0.5 mm.
Note: If your computer is having trouble or taking too long to mesh the part, you may need to increase the element size. However, this is a good place to start.
Next up in our series you’ll gain a better understanding of Component Mesh Factors. Learn what they’re all about here.
