At the moment i performing a transient Parameter study on CFX in Ansys Workbench.
Iam testing the thermal heat distribution for different cases (different sizes and input parameters) over 2 hours. When i click on update all points, the solver is calculating the first design point with all time steps (so 0-7200 s) . All the other design points are calculated with just two timesteps (7200-7220) Any tipss what iam doing wrong? |

In Pre you have multiple options for Time duration. There choose the option "Time per Run" and set 7200 s. Then it will add 7200 s each time you will continue the calculation.
If you want to start at t=0 each time, then you should change the Initial time. Change the option from "Automatic with Value" to 'Value" and set it equal to 0[s]. |

All this settings i have set, but if i start the parameter study
he still continue at the last time step from the previous design point (and so he cancel the simulation after 1 time step) |
