    Time-Dependent Analysis

      Dear Flow Simulation Forum Members,


      I have read the help files and am not sure if I am setting up my problem correctly.   My problem is as follows:


      I want to pulse a surface heat source; on for 3 seconds and off for 7 seconds.  I want to simulate one hour of operation or until the solid temperature has reached steady state.


      I have set up the problem as follows:


      General Settings:

            Time Dependent: checked


      Calculation Control Options:

           Finish Tab:

                 Finish Conditions:

                      Maximum Physical Time:



      Heat Sources:

           Surface Source:


                      Dependency: f(x)

                          Dependency type: F(time) - table

                               Table of values:

                                    value t          Toggle

                                         0 s          On

                                         3 s          Off

                                         10 s        On


      Does this correctly simulate the pulsing of my surface source 3s on, 7s off, for 1 hour?


      Thank you,
