The Rapid heating and cooling circuit density result shows the density of the various substances that are pumped through the rapid mold heating and cooling circuits, for both dual domain and 3D analyses. This result is generated from a rapid mold heating and cooling simulation using a Transient Cool analysis.
This result indicates what fluid is in the circuits at any given time, and therefore what stage of the cycle the process has reached. If your solution is not converging, the Rapid heating and cooling circuit density result might provide some insight. Take a look at the pressure settings in the boundary conditions.
Using this result
The Rapid heating and cooling circuit density result is best used in conjunction with the data in the analysis log. The analysis log indicates when the program transitions from one step to the next, and thereby helps you understand what is happening when looking at the Rapid heating and cooling circuit density result.
During the air purges, the density of the air is comparatively low, so the value for the Rapid heating and cooling circuit density result is fairly low. By comparison, the density of the steam is higher, and the value of the coolant is the highest.
to animate the result, and see how the Steam Quality result changes over the duration of the cycle. Things to look for
When viewing the Rapid heating and cooling circuit density result, watch for the following.
- The lowest density is provided during the air purges.
- The highest density is provided by the coolant.
- The variation in density during any given step of the cycle does not exceed about 3x the lowest value. If the variation is too great, this could indicate that the input pressure is too high.
