Time-dependent Internal Heat Generation
Dear all,

is it possible to define a time-dependent Internal Heat Generation in a solid sub-domain in CFX please?

if possible, can anyone show me where to look for the procedure please? i don't seem to find it in the help files.

Example of volumetric heat term:

q_volume=t*1[W s^-1 m^-3]

Apply as volumetric source to subdomain

Dear Edmund,

thank you for your prompt reply and help.

This is a linear volumetric heat time-dependent expression. how could i define a multi-step time dependent volumetric heat please?

i.e., my task is to apply 100W m^-3 at t=0, 500W m^-3 at t=5,500W m^-3 at t=10, 10W m^-3 at t=11, 10Wm^-3 at t=200, 0Wm^-3 at t=210.

Look up CEL expression for IF or STEP

or just use a user function.
