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. __________________ Thank you for your kind attention.
