Transient Parameter Study - To less timesteps
 

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)
