ANSYS Direct Optimization

I am using Direct Optimization on ANSYS Workbench 2019R1. I have an Icepak model with multiple parameters. I am running the optimization to minimize one parameter while keeping another derived parameter constant. 


I am having two scenarios which I do not understand. 


1. The optimization converges, but there are no candidate points. 


2. Candidate points are given but the optimization did not converge. 


I do not understand how it can give candidate points without converging, and how it converges and there are no candidate points. 


Can someone elaborate on this topic please?

i have quit the same issue.

I use the Optimization-Tool to  converge some Paramteters.

The Maximum Number of Candidates Value is 5,l but in the results no Candidate-points has been found and i dont know why.


Need help too!
