Hello,

in my test DoE I noticed that the values of the lift forces of the subsequent design points (DP1, DP2, ...) differ significantly from the initial value (DP0). In the Solver Manager, you can see that the values from DP1 onwards do not converge after 600 iterations, resulting in the larger lift force.

If I run the simulation of DP1 separately, the lift force converges and is in the range of that of DP0.

I suspect that the system is carrying over certain data from the previous simulation and that is why it comes to this progression. Now I wonder if there is a possibility to change the settings of the CFX project so that after each simulation of a DP the created data is automatically deleted, as you can do by right clicking on the solution surface.

Thanks for helping!

Hi MH1096 This mostly might be an initialization issue. You can check the initialization conditions by right-clicking the CFX solution cell > Properties > check Initialization Option. If it's set to the default value of "update from current solution data if possible" then it will continue from a solved solution. If it's set to "Update from Initial Conditions" it will start from the initial conditions defined in the setup. You can set it to the latter option and see if that works for you.

It actually worked. Thank you so much! You saved me a lot of time!
