I want to know that how i write a code of 3d Nano constriction geometry in oommf software. I attached the geometry if anyone have idea for code then please answer this question.

Launch OOMMF and create a new simulation by going to "File > New > Simulation." In the "Simulation Settings" dialog box, specify the dimensions and material parameters of your nanoconstriction geometry. You can do this by selecting the "Geometry" tab and then clicking on the "Edit" button next to the "Dimensions" field. In the "Geometry Editor" dialog box, use the drawing tools to create your nanoconstriction geometry. You can specify the dimensions of the geometry by entering numerical values in the fields provided. Once you have finished designing your nanoconstriction geometry, click "OK" to close the "Geometry Editor" dialog box and then "OK" again to close the "Simulation Settings" dialog box. To save your nanoconstriction geometry as an OOMMF script, go to "File > Save As" and select "OOMMF Tcl Script (*.mif)" as the file type. Then, enter a name for your script and click "Save."
To write a code for a 3D nanoconstriction geometry in OOMMF (Object Oriented MicroMagnetic Framework) software, you can follow the steps below:
This will create a Tcl script that you can use to run simulations with your nanoconstriction geometry in OOMMF.

Start by creating a new OOMMF project and selecting "Tcl" as the scripting language. Define the dimensions and other parameters of your nano constriction geometry, such as the width, height, and depth of the constriction, as well as the material properties of the constriction (e.g. exchange constant, anisotropy constant). Use the "rectangular mesh" command to create a mesh of your constriction geometry, with a specified number of cells in the x, y, and z directions. Use the "set mesh" command to specify the mesh you just created as the mesh for your simulation. Use the "set default units" command to specify the units you want to use for your simulation (e.g. meters, nanometers). Use the "set magnetization" command to specify the initial magnetization of your constriction. Use the "evolve" command to run the simulation and evolve the magnetization over time. Use the "output" command to save the simulation results to a file, such as an ".odt" (OOMMF Data Table) file.
Here is a general outline of how you can do this:
