高手帮解释一下 XFDTD 7中的 XACT是什么东东

从Remcom 上看到了XACT这个东东，本人想知道这是指的共性技术还是亚网格技术?
其英文说明如下：
XACT Accurate Cell Technology
Faster, More Accurate Simulations
XF7’s new XACT mesh reduces your simulation time while improving the accuracy of even the most intricate designs. Important geometrical features including complex curved surfaces and small gaps are resolved using an advanced sub-cellular conformal method. By representing input geometry more precisely, XACT mesh allows you to reduce computing resources while maintaining the accuracy of a full wave solver. Faster, more accurate simulations improve the throughput of your designs from start to finish.

就是conformal-FDTD 共形网格

偶?  ft2death 会用 7.0版的吗?和6.3的大不相同阿，我很晕。说实话我研究了半天7.0，没发现它有共形的功能，就只是觉得能并行！

7.0没有啊conformal FDTD阿， 这个XACT Accurate Cell Technology 是7.1才有的，我很想试试。 亚网格早在6.4就有了把。
