1、V12之施加随坐标变换的荷载在以往版本中 Workbench只能施加随时间变化的荷载，如果要施加随空间变化的荷载，只能借助于commands。V12在这点上有所改进，虽不是尽善尽美，也算是一个进步。目前 Workbench 只支持 pressure, line pressure, temperatue 和 thermal condition 这四种荷载进行空间变化，而且只用有一个变量。下面以pressure为例说明如何定义。先插入一个 Pressure, Defined by 必须是 normal toDetails of Pressure01改 Magnitude 为 TabularDeta
