Temperature Gradient

Solidification progresses through the melt as a result of the extraction of heat from the liquid at the solid/melt interface. Temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location
The temperature gradient is a dimensional quantity expressed in units of degrees per unit length

                   

SUTCAST simulation also gives isothermal contours and temperature gradients in a casting and assists foundry man to identify the solidification pattern and making the right decision to get the best result
