由 江枫思渺然 提交于 2021-02-19 03:27:28
问题 I am trying to use paraview to plot a xy plot. The plot I want is just a linear relationship between x and y. So I import my data file (data.csv) into paraview. My data is shown below: X Y 0 0 1 1 2 6 3 8 4 15 Then I set the delimiter to " ". After that I can see the data is sorted in x and y column. But I do not find a option to let paraview to plot the data. Any help? Thank you. Here is a screenshort of my interface: 回答1: Add a Plot Data filter while you have data.csv selected and click

OpenFOAM有俩种安装方式，第一种为直接安装，第二种为编译安装。直接安装的OpenFOAM由于网络问题不太稳定。本文介绍编译安装方法。注意：需要保证linux系统可以联网。 1. OpenFOAM安装 以下安装过程适用于Ubuntu20.04/19.10/18.10/18.04系统，以及原生OpenFOAM-3.0以上的版本，其他各版本可能会出现若干问题。 （1）安装好ubuntu系统，并 确保ubuntu可以联网 、确保内存 最好在10G以上 。 （2）进入Ubuntu桌面。通过Ctrl+Alt+T启动终端，在终端输入（分二次输入，直接全部复制进去）： sudo apt update sudo apt-get install build-essential flex bison git-core cmake zlib1g-dev libboost-system-dev libboost-thread-dev libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev 键入后会要求输入密码。注意，密码并未显示。回车后，会提示是否安装这些库，键入 y 后进行安装即可。这样，准备工作进行完毕。 （3）下载 OpenFOAM-8 以及 ThirdParty-8

Paraview create line segments from CSV with “width” data

问题 I want to create line segments in Paraview. The format of my input data for each line segment is as: x0,y0,z0,x1,y1,z1,width I have tried using "Line" command like: for i in range(600): l = Line(Point1=(uniform(0,100),uniform(0,100),0),Point2=(uniform(0,100),uniform(0,100),0)) But, I can't find a way to specify the width to each line segment. Your help will be much appreciated. Best Regards, Hamid Rajabi. 回答1: The Line object does not know about the width . It is only a list of connected

问题 I have a pvtu file with associated vtu files from which I want to display some data. If I load the pvtu in Paraview (5.6+), I get the following image when I choose Solid Color (White) and Surface With Edges: The mesh is clearly anisotropic close to the top boundary with almost flattened triangles; this is the expected behaviour. If I now load the same pvtu in Python and display the mesh in the following manner, import numpy import matplotlib.pyplot as plt import vtk gridreader = vtk

Create mesh from cells and points in Paraview

问题 I have a CSV file with stress data and geometry that I have exported from ANSYS Mechanical that I would like to visualize in Paraview. Each node has a bunch of stress data related to it. I managed import the points as a point cloud in Paraview but I want to recreate the ANSYS mesh as well. I thought that "programable source" in Paraview could be an alternative way and with some googleing I could probably figure out how to read the data in to numpy arrays but the fundamental question is, how

问题 I have a VTK file (unstructured grid) with points and cells . I can import the file and read it into using the meshio python package. If I type the command mesh.cells I see a dictionary called 'hexahedron' with an array made up of lists inside like this: {'hexahedron': array([[ 0, 162, 185, ..., 163, 186, 23], [162, 329, 351, ..., 330, 352, 186], [329, 491, 514, ..., 492, 515, 352], ..., [483, 583, 600, ..., 584, 601, 490], [583, 650, 656, ..., 651, 657, 601], [650, 746, 762, ..., 747, 763,
