@Samuel-Tu 具体忘了,网上搜下吧,可以设置每个软件调用独显还是集显

@Samuel-Tu 之前也遇到过这个问题,貌似是和独显集显相关的,paraview得用独显,可能是设置的过程被禁用了
-
@bestucan 感谢回复!已经Allclean了 ,另外,不更改重新跑了一遍又没问题了,就是对出现的问题感觉比较迷。。。
-
@Zhoujq 感谢回复!不是虚拟机,这种情况是第一次出现,以往的算例都能正常运行,查了下网上好像没人遇到过这种情况
-
有大神遇到下面的这种问题吗,就是算例突然停了,但不是算错的那种强制停,最下方的那行是个啥东西,不知道是啥原因,图是log日志里的
-
请问有人知道重叠网格里嵌套网格和背景网格二者之间的尺寸关系需要满足什么条件吗?另外,如果运动物体有薄壳结构(厚度0.02m),那在划分背景网格时尺寸是不是一定要小于0.02m?恳请回复!
-
@bestucan 感谢回复!
-
@nanxuan 不太清楚,印象中没遇到过这个问题
-
@nanxuan 运行内存多大 在编译时把其他进程都关了试试 可能新版要求更高了
-
@nanxuan 估计是运行内存太小导致的,建议单核编译,或者增加虚拟内存(存疑)

算的是一个流固耦合的算例,设置的时长为30s,时间步为0.0008s,但就像下面log文件所示,跑到21.6s就不动了,库朗数和时间步也都没有问题,可后台的算例仍在运行,不知道有人遇到过这种情况吗?

@xjwang 请问你的这个问题解决了吗,我也遇到这个问题,不知道咋回事,算例并行计算仍在继续,就是时间步不增加了
-
@bestucan 这也许是个好主意,可以试下,另外,还有个类似不倒翁的结构,这个有实现的思路嘛,特征就是结构一体化,上一半密度比水小,下一半密度比水大
-
@bestucan 外文也有在找,感觉不太好找
-
感谢老师回复!不过目前需要算一个类似封闭木桶的结构在迎浪下的运动响应,用可压缩变形来处理会不太符合实际情况,所以暂时没有考虑过这个做法,目前能想到的最接近的做法也只有在表面上开一个非常狭小的口把内外两个patch连接起来
-
或者换一个说法,OpenFOAM 能模拟密闭的具有一定厚度的壳状类浮体吗?
-
如题,想模拟一个浮体在波浪中的运动响应,该浮体下方固结一块密度较大的配重,请问有人做过相关的模拟吗?浮体和配重均是不规则形状的,需要使用rigidBody来引入patch,但未找着将这两个patch连接起来的方法,还求大佬指点下
-
@DY大世界 snappyHexMesh -overwrite,估计是这个问题
-
在dynamicMeshDict中rigidBody一共有五种type:cuboid;masslessBody;rigidBody;sphere;jointBody,前四种都会用,唯独最后的jointBody没用过,查了一下资料没找着相关说明,有人知道这个jointBody怎么用吗?
-
本人使用的是rigidBody,和sixDoFRigidBody不同的是,它有一项是transform,个人理解是用于从全局坐标系转到局部坐标系(动坐标系)的指令,所以如果动坐标系是固定在物体的重心处,transform中的向量项应该和centreOfMass是一致的才对,但是一算就死,后面试了下,把transform中的向量项写成(0 0 0)就能算,不过计算结果中会缺少部分自由度,有人遇到过这个问题吗?
-
@wwzhao 明白,感谢老师解答!
-
@wwzhao 关于字典文件的问题,我先是参考算例中的设置方法,弄成这样:
sixDoFRigidBodyMotionCoeffs { bodies { floatingObject1 { patches (floatingObject1); innerDistance 100; outerDistance 101; centreOfMass (2.0 0.5 1.0); // Cuboid dimensions radius 0.25; // Density of the solid rhoSolid 500; // Cuboid mass mass #calc "$rhoSolid*4/3*3.1415926*$radius*$radius*$radius"; // Cuboid moment of inertia about the centre of mass momentOfInertia #codeStream { codeInclude #{ #include "diagTensor.H" #}; code #{ scalar sqrLx = sqr($radius); scalar sqrLy = sqr($radius); scalar sqrLz = sqr($radius); os << $mass *diagTensor(sqrLy + sqrLz, sqrLx + sqrLz, sqrLx + sqrLy)/5.0; #}; }; } floatingObject2 { patches (floatingObject2); innerDistance 100; outerDistance 101; centreOfMass (3.5 0.5 1.0); // Cuboid dimensions radius 0.4; // Density of the solid rhoSolid 400; // Cuboid mass mass #calc "$rhoSolid*4/3*3.1415926*$radius*$radius*$radius"; // Cuboid moment of inertia about the centre of mass momentOfInertia #codeStream { codeInclude #{ #include "diagTensor.H" #}; code #{ scalar sqrLx = sqr($radius); scalar sqrLy = sqr($radius); scalar sqrLz = sqr($radius); os << $mass *diagTensor(sqrLy + sqrLz, sqrLx + sqrLz, sqrLx + sqrLy)/5.0; #}; }; } } report on; accelerationRelaxation 0.7; accelerationDamping 0.9; solver { type Newmark; } sixDoFRigidBodyMotionRestraint { linkedspring { body floatingObject; type linearSpring; anchor (3.1 0.5 1.0); refAttachmentPt (2.25 0.5 1.0); stiffness 100; damping 0; restLength 0.3; } } }
之后运行时就提示cannot find centreOfMass,但如果我将上述的bodies、floatingObject1等子目录删掉,像这样:
sixDoFRigidBodyMotionCoeffs { patches (floatingObject1); innerDistance 100; outerDistance 101; centreOfMass (2.0 0.5 1.0); // Cuboid dimensions radius 0.25; // Density of the solid rhoSolid 500; // Cuboid mass mass #calc "$rhoSolid*4/3*3.1415926*$radius*$radius*$radius"; // Cuboid moment of inertia about the centre of mass momentOfInertia #codeStream { codeInclude #{ #include "diagTensor.H" #}; code #{ scalar sqrLx = sqr($radius); scalar sqrLy = sqr($radius); scalar sqrLz = sqr($radius); os << $mass *diagTensor(sqrLy + sqrLz, sqrLx + sqrLz, sqrLx + sqrLy)/5.0; #}; }; patches (floatingObject2); innerDistance 100; outerDistance 101; centreOfMass (3.5 0.5 1.0); // Cuboid dimensions radius 0.4; // Density of the solid rhoSolid 400; // Cuboid mass mass #calc "$rhoSolid*4/3*3.1415926*$radius*$radius*$radius"; // Cuboid moment of inertia about the centre of mass momentOfInertia #codeStream { codeInclude #{ #include "diagTensor.H" #}; code #{ scalar sqrLx = sqr($radius); scalar sqrLy = sqr($radius); scalar sqrLz = sqr($radius); os << $mass *diagTensor(sqrLy + sqrLz, sqrLx + sqrLz, sqrLx + sqrLy)/5.0; #}; }; report on; accelerationRelaxation 0.7; accelerationDamping 0.9; solver { type Newmark; } sixDoFRigidBodyMotionRestraint { linkedspring { body floatingObject1; type linearSpring; anchor (3.1 0.5 1.0); refAttachmentPt (2.25 0.5 1.0); stiffness 100; damping 0; restLength 0.3; } } }
就能运行了,不过这样一来问题就是只有floatingObject2可以动,floatingObject1不能动,所以对这个问题比较迷惑,也不知道该如何解决
-
@wwzhao 感谢老师解答,还想问下,我该如何在dynamicMeshDict中实现用弹簧连接双浮体呢,找了找网上的资料,没能够找着相关资料
-
@wwzhao 老师,您是这方面的专家,能否帮忙解答一下呢?
-
请问下有哪位重叠网格大佬知道该如何在dynamicMeshDict中定义双浮体?我用的是v1906版本,一旦指定body1和body2,运行时就会出现cannot find centreOfMass的问题;
另一个是如何采用linearSpring连接两个浮体?因为在restraints参数中有一个anchor点和一个refAttachmentPt点,如果直接用两个refAttachmentPt点是否可行?相关的body该如何指定?
恳请大佬帮忙答疑! -
问题是这样:我想模拟水面上一个自由漂浮的物体,所以需要开放六自由度,相关设置是dynamicMeshDict文件中的constraints关键词,但是此关键词若仅指定一个axis,就只是开放了绕这个轴的转动,有人知道六自由度同时开放该如何实现吗?axis是都不指定还是都指定?相关指定方法怎么实现?谢谢大佬!
-
@东岳 明白,感谢老师~
-
有人知道计算到后面deltaT变得非常小(-10次方级别)是怎么回事吗?而且还是越来越小,字典文件中设置的是0.0005可调整时间步,另外,在计算过程中再更改controlDict中的参数还会生效吗?
-
@东岳 用的overOlaDyMFlow,但是都已经跑了快四个周期才出的这问题
-
如题,出错情况如下,但是和通常情况下的浮点数例外又不太一样,有人知道这个错误是什么原因引起的吗?上一个时间步的库朗数0.87,字典中设置的最大库朗数为0.9,和这个有关系吗?

先对路过的大佬表示下感谢!
我看到不同算例中使用约束有constraints和restraints两种不同关键字,它们有区别吗?其中fixedPoint和fixedLine能理解,但fixedAxis代表什么呢?另外,我模拟的是浮体在水面上自由漂浮,不受约束,设置时直接将这个关键字删除了,但是运行过程发现浮体不动了,这是怎么回事呢? -
把网格抠除?
-
@一颗鸭蛋 谢谢你的回答,我用的重叠网格,贴体网格和背景网格的长宽都是1:1且一样大,然后就不知道问题出在哪里了

-
如图所示,不太了解这个错误是由于什么原因引起的,求解器是overOlaDyMFlow,恳请路过的大佬帮忙解答一下! -
@东岳 解决了,确实是内存的问题,把并行编译核数减少就可以了
-
@东岳 但是编译过程出现了下列这个问题后就停止编译了,首先以为是路径问题,但是改过之后再次编译还是这个问题,这个是什么原因呢?
-
@东岳 对了李老师,我下载完v1906版本后仍然按照东岳流体网站上的安装步骤指南操作就行了吗?
-
明白了,感谢李老师~
-
采用的是编译安装
-
本人小白一枚,先在此对前来答疑的大佬表示下感谢~
问题:按照东岳流体网站上的安装指南在ubuntu下安装了of7,但是没有找到诸如overInterDyMFoam等动网格/重叠网格算例,请问是怎么回事呢?在哪里可以找到这部分的算例下载地址呢?求助各位帮忙!
