关于库中网格信息读取的相关问题

金哲飞

请问想要rigidBodyDynamics库中调用到某patch网格面上的信息。现在想到的方法是在库中找相关的继承函数，再类似mesh.boundaryMesh()。但是这个想法没能实现。请问这种思路是否可行。或者OpenFOAM中是否存在类似直接调用constant/polyMesh中网格信息的操作~希望能给出建议~

freevector

没问题呀，可以参考applications/test/mesh/Test-mesh.C文件

@freevector 谢谢老师~ 我找到了一个方法，用lookup指针去找model_.time().lookupObject<fvMesh>("region0")，您的方法我有个地方不太理解，就是runTime提示没有申明，不太明白什么意思~
