CST error

[pooja sudha]

Hey,
I am finding the following errors in CST while simulating and still after that simulation is running. Will the result affected by this?

Detected possible stagnation of the iterative solver (7.735998e-01 after 250 iterations.)
Please consider aborting the solver run, and check your simulation setup.
Detected possible stagnation of the iterative solver (4.021943e-01 after 500 iterations.)
Please consider aborting the solver run, and check your simulation setup.
The solver stopped because the maximum number of iterations (500, used for automatic solver choice) has been reached.

The result you get is probably not reliable since the solver has stopped because it has reached maximum iterations. You can also check Convergence and Adaptive Meshing passes to make sure your results are good enough.

It means the optimization setup has reached to the conclusion that no better solution exist for the problem and you can solve this issue by either adding more variables to the optimization or changing the range of the variables in the optimizer and the 2nd thing you can do is increase the number of iteration as it is using default 500 but to be honest if some solution did not converge in 500 it means it will not converge but non convergence may not mean the no solution it may mean the improved solution so check the results and see if they are better or in the direction you want and then relax the range of variables in optimization or remove some and add some new
