Hi,

It is very crazy that I cannot use the .dri file in the "AlCu_Equiaxed" example using MICRESS 4.08 version. That is because there is no need to input the following information:

# Enthalpy of phase 0 (LIQUID)? ([J/cm^3])
0.0000000
# Specific heat capacity (Cp) of phase 0 (LIQUID)? ([J/(cm^3*K)])
2.5000000
# Enthalpy of phase 1 (FCC_A1)? ([J/cm^3])
-2000.0000
# Specific heat capacity (Cp) of phase 1 (FCC_A1)? ([J/(cm^3*K)])
2.5000000

And the results are definitely different from those presented in your example. Why this case can occur?


Sincerely yours,

Dear sunny,

the example you are referring to is probably from Version 5.3. From Version 5.4 we decided to calculate latent heat directly from the thermodynamic database used in the example which is much better and easier. Combining coupling to thermodynamic data with manual input of latent heat data is definitively inconsistent, so we intentionally omitted this possibility.
Of course, this update also changes the results of the "AlCu_Equiaxed" example. Please note that the examples given with the MICRESS releases are useful for illustrating the input structure of the software. They are not always reflecting fully realistically the underlying physical processes!

PS: The examples on our download area urgently need to be updated!

Hi, Bernd,

Thank you for your reply. It is better to directly use the thermodynamic database.

Wish to see powerful examples for our MICRESS users!


Yours,

Sunny
