Hello candidate,
An aerostructural analysis engineer have to learn Nastran/Patran, Ansys, OEM customised or developed softwares.

A design engineer would use softwares like CATIA, Solid Works.

A CFD engineer Ansys Fluent, Star CCM, etc.

A controls Engineer would use Matlab/Simulink .

There could be many more according to the specialized field of the engineer. So the softwares used by an aerospace engineer completely depends on the domain of work they are into.

Hope that helps thank-you.
