In this paper, we study a triad of inhomogeneous scalar fields, known as ”solid”, as a source of homogeneous but anisotropic dark energy. By using a dynamical system approach, we find that anisotropic accelerated solutions can be realized as attractor points for suitable choices of the parameters of the model. We complement the dynamical analysis with a numerical solution whose initial conditions are set in the deep radiation epoch. The model can give an account of a non-negligible spatial shear within the observational bounds nowadays, even when the later is set to zero at early times. However, we find that there is a particular region in the parameter space of the model in which the Universe isotropizes. The anisotropic attractors, the particular isotropic region, and a nearly constant equation of state of dark energy very close to $-1$ are key features of this scenario. Following a similar approach, we also analyzed the full isotropic version of the model. We find that the solid can be characterized by a constant equation of state and thus being able to simulate the behavior of a cosmological constant.

在本文中，我们研究了不均匀的标量场三元组，称为“固体”，它是均匀但各向异性的暗能量的来源。通过使用动态系统的方法，我们发现，各向异性加速解决方案，可实现作为模型参数的合适的选择吸引点。我们用数值解补充了动力学分析，其初始条件设定在深辐射时代。该模型可以说明当今观测范围内的空间剪切是不可忽略的，即使在较早的时候将其设置为零也是如此。但是，我们发现模型的参数空间中存在一个特定区域，在该区域中各向同性。各向异性吸引子，特定的各向同性区域以及非常接近于$-\mathrm{1个}$是此方案的关键功能。遵循类似的方法，我们还分析了模型的完整各向同性版本。我们发现，固体可以用一个常数状态方程来表征，因此可以模拟宇宙常数的行为。
