>PreCAST Load the mesh file and go to Materials / Assign Stress during solidification PreCAST Load the mesh file and go to Materials / Assign Stress during solidification only will be simulated, casting will be thus considered as full ‘not empty’ (select materials suitable for stress simulation)

>PreCAST We will consider here the die as rigid and the casting will be PreCAST We will consider here the die as rigid and the casting will be elasto-plastic. Select a material that is consistent with the thermal properties assigned previously

>PreCAST BC displacements need to be set in order to avoid translation or rotation PreCAST BC displacements need to be set in order to avoid translation or rotation of the model. Note that a rigid die won’t move as it is considered as fully constrained.

>PreCAST ProCAST will stop the calculation as soon as all casting temperatures are below PreCAST ProCAST will stop the calculation as soon as all casting temperatures are below 400°C (Tliquidus of the selected material is 522°C)

>PreCAST Another possibility is to stop the calculation as soon as the casting is PreCAST Another possibility is to stop the calculation as soon as the casting is ejected out of the die.

>For stress calculations, PIPEFS must be set to 0.  PreCAST For stress calculations, PIPEFS must be set to 0. PreCAST

>PreCAST To activate stress model set STRESS 1 Select adequate storage and calculation frequency PreCAST To activate stress model set STRESS 1 Select adequate storage and calculation frequency

>PreCAST Save and exit PreCAST PreCAST Save and exit PreCAST

>ProCAST Run the simulation ProCAST Run the simulation

>Other possibilities In order to take into account the mold temperature distribution  reached Other possibilities In order to take into account the mold temperature distribution reached after several cycles (Steady state regime), the mold temperature distribution obtained in a previous calculation can be used as initial temperature for the stress calculation Thermal distribution of die after 10 cycles

>Other possibilities We can also start a coupled thermal-stress calculation using the temperature distribution Other possibilities We can also start a coupled thermal-stress calculation using the temperature distribution of the casting after a filling calculation Thermal distribution of casting just after filling
