<1D Domain Wall Motion Simulator> <Fig. 1 Output dialog box of the simulator>
 This is the standalone DW (Domain Wall) motion simulator based on the wellknown 1D collective coordinate approach in E. Martinez, S. Emori, N. Perez, L. Torres, and G. S. D. Beach, JAP 115, 213909 (2014).
 The simulator adopted all known influences including the 3dimensional external fields, spin transfer torque with nonadiabatic contribution, spin Hall effect, Rashba effect, and DzyaloshinskiiMoriya interaction.
 The detail information and usage of the simulator are presented in <H. Kim, S. W. Heo, ChunYeol You, AIP Advances 7, 125231 (2017)>.
 It can calculate the DW position, velocity, the internal magnetization angle of the DW, and DW tilting angle as shown in Fig. 1.
 The definitions of the angles and the coordinate system is shown in Fig.
 The simulator is implemented for Windows® and running with the MATLAB® runtime library.
 You can download the <executable> or <installer>
 The executable requires proper Windows 64bit version of the MATLAB Runtime for R2016b),
 Installer will install MATLAB Runtime automatically.
 You can open input dialog box as shown Fig. 2.
<Fig. 2 The input dialog box>
<Fig. 3 Definitions of the angles and coordinate system>The input parameters for material layers and running options are given in the configuration dialog window shown in Fig. 2. You can save and open all parameters as a plain text file, and your calculation results are saved as a plain text file separately. Fixed current density : If you set step and stop for current density to zero, the simulator calculates results only for a specific current density. Multiple current densities : If you set appropriate nonzero values for the step and stop for current density, it calculates simulation results for each current density and shows the results together For the multiple current densities, the simulator also calculates the DW velocity vs. current density results in the separated new windows as shown in Fig. 3.
<FIg. 4 The output dialog box for multiple current density calculations> The code is developed by MATLAB, and only executable file will be distributed (not source code), and if you have any question, suggestion, and help, contact to me. (cyyou@dgist.ac.kr)
