The storage of unsymmetricalmatrix is completed. The program can calculate and analyze with the constitutive model adopted the non-associated flow rule.
实现了非对称矩阵的存储，程序能够采用非关联流动法则的本构模型进行计算分析。

But the scale of the problem that can be solved by BEM is greatly limited, because the matrix of the system equations generated by BEM is fully populated and unsymmetrical.
