在本文中，我们提出了在SOFA框架中的多重网格ODE求解器的实现。通过结合粗网格的稳定性优势和细网格的瞬态细节保持优点，多重网格ODE求解器比基于单级离散的经典ODE求解器计算效率更高。随着SOFA框架在许多手术模拟项目中的广泛采用，将此多重网格ODE求解器引入SOFA的ODE求解器池将使整个社区受益。这一贡献可能在手术模拟研究界产生广泛的影响，因为在单分辨率系统中，构成现实的交互式组织响应（以大元素为前提）与模拟中代表临床相关关键组织的需求（通常由小元素组成）直接冲突。
In this paper, we present the implementation of a Multigrid ODE solver in SOFA framework. By combining the stability advantage of coarse meshes and the transient detail preserving virtue of fine meshes, Multigrid ODE solver computes more efficiently than classic ODE solvers based on a single level discretization. With the ever wider adoption of the SOFA framework in many surgical simulation projects, introducing this Multigrid ODE solver into SOFA's pool of ODE solvers shall benefit the entire community. This contribution potentially has broad ramifications in the surgical simulation research community, given that in a single-resolution system, a constitutively realistic interactive tissue response, which presupposes large elements, is in direct conflict with the need to represent clinically relevant critical tissues in the simulation, which are typically be comprised of small elements.
