DEPENDENT TIME HEAT FLUXES

Hello,

I'm new in Altair Hypermesh and I'm doing a thermal analysis of an electrospindle.

 

I have to analyze the grid temeperatures in the following case:

There is a bearing in one extrem of the spindle and another one in the other extreme. They generate a constant heat flux, but with a different value. Besides, the electric motor is another heat source.

With the aim of evacuate the heat, I apply a negative flux in housing's Surface. 

 

The problem is that I want to do a heat transient analysis, in which the negative flux is always active, but the bearing's and the motor's fluxes are disabled when 10 minutes have been passed. 

 

Anyone knows how I can introduce a flux that depends of the time?

 

Greetings,

DavidSol.

    Hi @DavidSol

     

    maybe this tutorial from OS documentation might help you:

    OS-T: 1090: Linear Transient Heat Transfer Analysis of an Extended Surface Heat Transfer Fin

    This tutorial outlines the procedure to perform a linear transient heat transfer analysis on a steel extended-surface heat transfer fin attached to the outer surface of a system generating heat flux (Example: IC engine). The extended surface heat transfer fin analyzed in this tutorial is one of many from an array of such fins connected to the system.
