How to set the segmented temperature

Post by Ls_Thu » Tue Mar 05, 2019 3:08 am

Dear Bernd,

may i ask how to set the segmented temperature with Miccress 6.3? (for example 650C for 1min and then 800 for 30s)

Best regards,

Sai

Dear Sai,

For defining time-dependent (bottom) temperature you should use the "connection points" in the section "Boundary Conditions" in the input file:

# Boundary conditions
# ===================
# Type of temperature trend?
# Options: linear linear_from_file profiles_from_file
linear
# Number of connecting points? (integer)
3
# Initial temperature at the bottom? (real) [K]
923.15
# 1 Connecting point, time t [sec]?
60.00000000000000
# 1 Connecting point, temperature
923.15
# 1 connecting point, temperature gradient in z-direction (real) [K/cm]
0.0000
# 2 Connecting point, time t [sec]?
60.01
# 2 Connecting point, temperature
1073.15
# 2 connecting point, temperature gradient in z-direction (real) [K/cm]
0.0000
# 3 Connecting point, time t [sec]?
90.00000000000000
# 3 Connecting point, temperature
1073.15
# 3 connecting point, temperature gradient in z-direction (real) [K/cm]
0.0000
...

Temperature is interpolated linearly between the Connection points. If you have many connection points, it may be more convenient to read them from file ("linear_from_file"). Then, the extra input file should contain three columns with the time, temperature and temperature gradients of the Connection points.
