Hi @D KUSHAL KUMAR,
You can save the mesh obtained from an '.stl' file using the PDE toolbox in a text file using the following steps:
  • Create a PDE model using 'createpde' function.
  • Obtain the geometry into the model from the '.stl' file using 'importGeometry' function.
  • Generate the mesh using 'generateMesh' function.
  • Now after obtaining the mesh, we can obtain the 'Nodes' and 'Elements' and use the 'dlmwrite' or 'writematrix' function to save them individually in text files.
The following MathWorks documentations can be referred:
'createpde': https://www.mathworks.com/help/pde/ug/createpde.html
'importGeometry': https://www.mathworks.com/help/pde/ug/pde.pdemodel.importgeometry.html
'generateMesh': https://www.mathworks.com/help/pde/ug/pde.pdemodel.generatemesh.html
'dlmwrite': https://www.mathworks.com/help/matlab/ref/dlmwrite.html
'writematrix': https://www.mathworks.com/help/matlab/ref/writematrix.html
Thanks.
