翼型参数化方法——CST(Class function/shape function transformation)(附RAE2822翼型拟合代码) 在翼型优化前首先要对翼型进行参数化处理,我们知道一般翼型都由一系列的点表示,这个方法的好处是足够精确,只要支持样条线的软件都可以精确将翼型形状复现出来,但是缺点在于参数太多,直接将点集作为优化的参数一方面对计算资源的...
virtual function和类的多态性有关,使用户在设计和实现类时不需要担心句柄指向的对象类型是父类还是子类,只要通过虚方法,就可以进行动态绑定,或者SV中称为动态查找方法(摘自红宝书)。 简单理解就是,virtual function是基类中的函数模板,可在派生类中使用新代码重写该函数模板’,它存在对的目的就是为了后续能够重写该...
