Right-side symmetric wing does not work for aerostructural analysis.

[kanekosh]

Description

Aerostructural analysis (both tubular and wingbox) does not work with right-side symmetric wings. Currently, only the aerodynamic analysis/optimization can handle right-side wings as fixed in PR #381 .

Most of the examples in OAS use left-side symmetric wing, therefore this bug does not affect most of the cases.
Exception is the OpenVSP-generated symmetric wings, which sit on the right-side plane (as reported in #396 )

Steps to reproduce issue

1. Copy any aerostructural example with a symmetric wing, and flip the mesh to obtain the right-side mesh:

mesh = mesh[:, ::-1, :]
mesh[:, :, 1] *= -1.0

2. Run aerostructural analysis with the flipped mesh.

Current behavior

Aerostructural solver fails.

Expected behavior

The right-side wing results should be the same as the original left-wing results.
