Powder Properties dialog
The Powder Properties tab enables you to specify the details of your feedstock so you can run a powder injection molding simulation.
| Dialog element | Explanation |
|---|---|
| Powder radius | The powder radius default value is 10 microns. For a more accurate solution, enter the value as provided by your material supplier. |
| Initial powder volume concentration | The initial powder volume fraction is the percentage of powder in the feedstock, as provided by your material supplier. |
| Maximum powder volume concentration | The maximum powder volume fraction is the maximum possible concentration of powder in the suspension. 68% is a reasonable estimate if you don't know this value for your material, and is the default value. |
| Particle stress coefficients | The more information you enter about your feedstock, the more accurate your simulation will be. Kn is a fitted parameter, which increases the powder segregation effect as it is increased. The default value is 3.0. Lambda 1 is a measured value from experimental data, and represents the normal stress tensor in the flow direction. The default value is 1.0. Lambda 2 is a measured value from experimental data, and represents the normal stress tensor in the perpendicular flow direction. The default value is 0.8. Lambda 3 is a measured value from experimental data, and represents the normal stress tensor in the curl direction. The default value is 0.5. |
