2.修改Fluent的udf.bat编译文件 例如我的ANSYS安装在D盘的Program文件夹下,在D:\Program Files\ANSYS Inc\v160\fluent\ntbin\win64下找到udf.bat文件,打开udf.bat文件,修改对应本机安装的microsoft visual studio版本的路径。详细请参考微博链接(同样十分感谢博主的分享): http://blog.sina.com.cn/s/blog_4a0a8...
/* compute pressure force on body by looping through all faces */ force = 0.0; begin_f_loop(f,t) { F_AREA(A,f,t); force += F_P(f,t) * NV_MAG(A); } end_f_loop(f,t) /* compute change in velocity, that is, dv = F * dt / mass velocity update using explicit Euler ...
看到好多虫友用到Compute_Force_And_Moment (domain, tf, CG, force, moment, true)这个函数在udf中...
在“机体”的udf中,我们通过两个Compute_Force_And_Moment 函数分别对“机体”和“胸鳍”的受力进行计算: Compute_Force_And_Moment (domain, yi, x_cg, f_glob, m_glob, TRUE); Compute_Force_And_Moment (domain, ti, x_cgt, f_globt, m_globt, TRUE); 然后以前进方向的力的和除以质量1.0得到加...
但是如果同时求多个 机翼的受力Compute_Force_And_Moment (domain, tf1, x1_cg, f1_glob, m1_glob,...
求助,有用过COMPUTE_FORCE_AND_MOMENT这个函数的吗 只看楼主收藏回复 蒂想 1L喂熊 1 我想模拟转子叶片在水的阻力下减速的过程。试算说明: 如图,中间是转子,包含转子的区域(rotor)与外围流域(stationary)以interface隔开,先给rotor域一个转速,一段时间后使其在水的阻力下减速。UDF编译成功,但是运算一段时间后就...

15.所述第一udf程序中,将海空多栖航行器的固有属性变量和初始时刻的运动参数作为全局变量,在define_execute_at_end宏下,利用compute_force_and_moment语句提取当前时间步结束时刻航行器的表面流场载荷,利用线性简化后的航行器动力学方程计算得到加速度;再根据线性离散化的运动学方程得到下一个时间步内航行器的运动参数...
I am writing a UDF for parallel computing at the moment. I am using the Compute_Force_And_Moment function. But I am not sure if I need to adjust the use of it in parallel processing. Since i didn't find much information on the web i wrote this function, with which i will investiga...
