Hi experts,

 

I want to define varied temperature according to time/ timestep using Surface Initialize function.

In tab Curve fit variable, I can not find time/ timestep.

Anyone please help instructing me using this tool.

 

Thanks in advanced!

    The 'Initialize' set is to set the initial conditions for the first time step - then things move on from there as the equations are solved.

    If you're trying to define boundary conditions, where the temperature changes in time, you would do that with a multiplier instead.

    When you're in the boundary condition definition panel, you'll see the icon with f(t) and a pull-down to the right.  You can either select an existing multiplier, or select the 'Create New' to define a new multiplier - as a function of time or time step.
