using sliding mesh问题

chengch

using sliding mesh 例子中要先进行rotor.msh 和 stator.msh
1.Start tmerge by typing utility tmerge -2d at the system prompt.
2. Provide the mesh le names, rotor.msh and stator.msh, as prompted. Provide
scaling factors of 1 and translations and rotations of zero for each mesh le. Save
请高手指点：怎么才能启动tmerge，tmerge是先启动fluent，再输入tmerge -2d？ 还是merge是另外一个模块，需要安装相关的软件。谢谢了
