请问一下四面体单元和六面体单元的积分器和组装器应该选择哪种,也是用LinearElasticityOperatorIntegrator,和BilinearForm.assembly吗?

你的问题还不够明确,你要求解的方程是哪一类方程,想用什么方法?
Sorry, something went wrong.
求解三维固体力学问题,想用六面体单元或者四面体单元,目前卡在了HexahedronMesh中的shape_function 变量中的bc,输入的bc的结构在函数内调用爱因斯坦求和时就会报错。我的bc输入的是,bc = (((1 - xi) / 2, (1 + xi)/2), ((1 - eta)/2, (1 + eta)/2), ((1 - zeta)/2, (1 + zeta)/2))。
return np.einsum('im, jn, ko->ijkmno', phi[0], phi[1], phi[2]).reshape(-1, ldof) 六面体中的shape_function,为什么形函数是六阶张量ijkmno?不应该是三阶吗?
bc似乎应该输入的是拉格朗日多项式?
