WebbIf a particular geometry optimization calculation fails to converge, click the Restart button in Job Manager, and view the last computed geometry. If this is different than the initial geometry, what does this mean about the stability of the initial geometry? Construct a table with columns for initial geometry and optimized energy. WebbTidal turbine blades typically require 3–5 airfoils for stacking along their tidal spreading direction. Therefore, the airfoils of the seagull, long-eared owl, and sparrowhawk were selected as initial airfoils for optimization. The relative thickness, camber, and trailing edge thickness of the three initial airfoils were different.

If the geometry optimization is failing to converge fairly often, it is probably better to not try to run the calculations automatically in sequence and to instead check on the geometry before starting the excited state calculation. Having said that, there is a way to define a sequence of Gaussian jobs that I think could fit your use case. bilson sports turlock ca
