Functionally time-dependent boundary conditions

1

Hello!

Is CalculiX able to set functionally time-dependent boundary conditions?

I need to define irradiated heat power to faces of object as a function of time…

What you are looking for is called amplitude in CalculiX. You can define it this way:

*AMPLITUDE, NAME=amplitude_name
time, value, time, value, ...

Then call it in radiative heat flux definition like that:

*RADIATE, AMPLITUDE=amplitude_name

if you want to scale the sink temperature. Or like that:

*RADIATE, RADIATION AMPLITUDE=amplitude_name

if you want to scale the emissivity.

Thank you, Calc_em!
I definitely need to read the manual…
