Temperature result shows the temperature distribution of the plastic at current time step.
From Temperature result, you can perform the following actions and modify design or analysis settings accordingly:
Determine which region has high frictional heating
Near the gates and low thickness region, the flow resistance becomes very high. This will lead to frictional heating of the plastic melt. Simply check if there is any temperature rise near the gate and low thickness region from Temperature result.
Check if the temperature variation corresponds to the process condition or design change
In most cases, designers modify the product design or process condition to get optimized results. When you change, say wall thickness, the temperature distribution will change because thicker cavity is harder to dissipate heat to the mold.
