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 ...
I used both CFD-POST and Fluent post-processing tool to show the velocity vector in a certain surface. The velocity magnitude by these two tools are different. Why? And how to fix the difference? How can get the same result by CFD-POST as the one by Fluent post-processing tool? Thanks...

Velocity vector sweep for simulations #1 coke1997 New Member Álvaro Join Date: Jun 2022 Location: Spain Posts: 4 Rep Power:4 Hi Foamers! I was wondering if there was any option to run SimpleFoam simulations for a sweep in angles of attack without the need of being changing the velocity...
根据上图的结果可以推测:writeData 的功能主要是将变量或参数的设定值(标量)写入到结果中,而 writeEntry 则是将设定的边界上的变量值以列表 (List)形式写入到结果中,value 作提示符使用。为证实这一推测,将 parabolicInletVelocityFvPatchVectorField.C的write函数中b的输出修改为如下形式:...

In the present work, coherent structures were detected by the Q-criterion which is the second invariant of the velocity gradient tensor28. In non-Newtonian flow, coherent structures interact with the viscosity with complex dynamics that is still under investigation29. Fig. 1d shows a region of ...
An example is provided in attachment. In this example, a first DEFINEONDEMAND stores the residual values of Pressure (= Mass Imbalance) X,Y and Z velocity, and the temperature in 5 UDMs. A second DEFINEONDEMAND use a general way to access any post processing variable with CPOSTVAR. In...
P_VEL(tp) is a vector, which contains P_VEL(tp) [0] - velocity in x direction, P_VEL(tp) [1] - in y direction and P_VEL(tp) [2] in z direction. in case you need velocity magnitude, you can use this Code: real v = NV_MAG(P_VEL(tp)); ...
