Define Materials

3.  Define material properties.

Define the sand mold properties as material number 1.  These are not functions of temperature.
  1. Main Menu:  Preprocessor
         Material Props
              -Constant-Isotropic
  2. OK to define material number 1  -»
  3. Enter 0.054 for DENS  -»
  4. Enter 0.025 for KXX  -»
  5. Enter 0.28 for C  -»
  6. OK  -»

The metal casting is defined as material number 2.  These properties change significantly as the metal cools down from the liquid phase to the solid phase.  Therefore, they are entered in a table of properties versus temperature.

  1. Main Menu:  Preprocessor
         Material Props
              -Temp Dependent-Temp Table
  2. Enter 0 for T1  -»
  3. Enter 2643 for T2  -»
  4. Enter 2750 for T3  -»
  5. Enter 2875 for T4  -»
  6. OK  -»

FIrst define the temperature dependent thermal conductivity.

  1. Scroll down and choose Th conductivity  -»
  2. Choose KXX  -»
  3. Enter 2 for Material reference number  -»
  4. Enter 1.44 for C1  -»
  5. Enter 1.54 for C2  -»
  6. Enter 1.22 for C3  -»
  7. Enter 1.22 for C4  -»
  8. Apply  -»

Next, define the temperature dependent enthalpy.

  1. Choose Enthalpy  -»
  2. Enter 2 for Material reference number  -»
  3. Enter 0 for C1  -»
  4. Enter 128.1 for C2  -»
  5. Enter 163.8 for C3  -»
  6. Enter 174.2 for C4  -»
  7. OK -»
