**//Description//**

XConditionInstance是边界条件在分析步中的实例化表达，它封装了边界条件的实例状态以及实例系数，它的类型标识为“CCNDINSTANCE”。XConditionInstance从边界条件的原型构建，属且仅属于一个XLoadCase，它将边界条件应用在分析步所指定的网格上并离散得到可以直接被求解器所使用的数据，当同一个分析步存在多个工况时，各工况所包含的条件实例应按顺序一一对应，且从第二个工况开始，工况所包含的条件实例可参考第一个工况对应实例的网格对象数据（不需要重新离散应用对象），仅需按照实例的设定重新构建条件数据即可，既可以节约内存又可以提高运行速度。

条件实例将边界条件与分析步解耦，解决了边界条件在不同分析步中的耦合问题，尤其是对于单点约束和多点约束可能导致的约束冲突以及局部坐标系的冲突，可在分析步内统一处理，使得多工况多分析步应用可以有更大的弹性空间定制专用的业务流程。
