Magnetic Line Plotting

Configuration

This project is configured using Visual Studio, using external libraries such as Eigen, Yaml, etc., these external libraries are managed by vcpkg

In my environment, the project should be built under Release and x64 mode, and vcpkg should have the packages as follow:

eigen3:x64-windows-static

fmt:x64-windows-static

yaml-cpp:x64-windows-static

Every time, in the initialization process, calculate the magnetization process and calculate the field around the surface of each micro-robot, the torque to each ball, then based on the field generate the magnetic line’s start points. In the first step, move all the test particles to form the magnetic line.

Run the project

To run the project, you should enter into ./MagneticLinePlotting/Binary/Release/ and run Demo.exe with the command line parameters.

• -t 0 two balls and each ball contains three chains
• -t 1 two balls and each ball contains three disks with the ratio of short axis and long axis ba
• -t 2 two uniform balls
• -t 3 two peanuts and each peanut is formed by two balls, each ball contains three disks with the ratio of short axis and long axis ba
• -t 4 seven balls and each ball contains three disks with the ratio of short axis and long axis ba
• -t 5 seven uniform balls
• -t 6 same as -t 1 but with different orientation
• -t 7 three balls arranged like an equilateral triangle and each ball contains three disks with the ratio of short axis and long axis ba
• -t 8 four balls arranged like a square and each ball contains three disks with the ratio of short axis and long axis ba
• -t 9 five balls arranged like three equilateral triangles and each ball contains three disks with the ratio of short axis and long axis ba

• -t 11 three balls arranged in a special shape and each ball contains three disks with the ratio of short axis and long axis ba
• -t 12 seven balls arranged in a hexagon and each ball contains three chains
• -t 13 seven uniform balls arranged in a hexagon
• -t 14 one ball contains three disks
• -t 15 like -t 11 but another special shape
• -t 16 like -t 7 but uniform balls
• -t 17 like -t 8 but uniform balls
• -t 18 like -t 17 but another shape
• -t 19 like -t 9 but uniform balls
• -t 20 like -t 10 but uniform balls
• -t 21 two balls and each ball contains single bundle

Process

• If you just want the magnetic line drawn in the plane not all the space, please turn on PLANARMOTION
• If you want to draw the total field not only the field by the micro-robots, please turn on DRAWALLFIELD
• If you want to change the allowed space to draw the magnetic line, feel free to change the range in bool collide2particle(const VectorDd &) const
• In the void printTorque(), there is some options for you to choose which torque to print
• If you want to rotate the external field, please turn on ROTATEEXTERNALFIELD
• If you want to test the interaction just for one ball, please turn on TESTONEBALL
• If you want to make the lines denser, please add the limitation of the cnt in void generateSampleParticle()
• If the distribution has any symmetric, please turn on the corresponding manipulation after generate the test particles in void generateSampleParticle()
