大佬们 CFD-Post绘制矢量图时报错'Velocity' is not a Vector Variable 是什么原因呢 ...
例如：你希望通过一个变量$vice来动态的组织一个字符串。Jack is a $vicemaniac.本来变量是$vice现在却变成了$vicemaniac，这样Veloctiy就不知道您到底要什么了。所以，应该使用规范的格式书写 ： Jack is a ${vice}maniac 现在Velocity知道变量是$vice而不是$vicemaniac。注意：当引用属性的时候不能加...
(not)(3)循环:foreach下面是一个例子:<ul>I#foreach( $product in $allProducts )<li>$product</li>iI I#endI I</ul>$allProducts 的内容可以是 Vector > Hashtable 或ArrayList ,每次取出一个值赋值给 $product ;返回的值是一个Jav 19、a对象,可以用来引用具体的方法。下面的例子假设$allProducts ...
Obviously, the velocity field, which is a vector, and the velocity potential, which is a scalar, are different. 2. Divergence, gradient, and rotation a. Divergence of a vector field Suppose we are using div v to represent the divergence of the velocity field v; it should be defined as ...
1 This is pine. 2 This is oak. 3 This is maple. 每次循环$list中的一个值都会赋给$element变量。 $list可以是一个Vector、Hashtable或者Array。分配给$element的值是一个java对象,并且可以通过变量被引用。例如:如果$element t是一个java的Product类,并且这个产品的名字可以通过调用他的getName()方法得到。
The Velocity template resource is, by default, hot reloadable for both file and classpath resources (expanded jar). If you setcontentCache=true, Camel will only load the resource once, and thus hot reloading is not possible. This scenario can be used in production, when the resource never ...

When considering the flow across a rotating element or rotor blade, the relative velocity (W) is important and is usually parallel to the rotating velocity. Vectorially, the relative velocity is defined as: (9-1)W→=V→−U→ where U→ is the tangential velocity of the blade. ...
