Use MATLAB to call ANSYS

  In matlab, I use statements like this "s1="E:ANSYS2022ANSYSv221ansysbinwinx64ANSYS221.exe -b -i C:UsersLYDesktoptesttxt write to override experimenttest01 (test).txt -o C:UsersLYDesktoptesttxt to write override experiment"; "to call ansys and execute the command stream I've written.Now I hope that in this way I can save the calculated stress contour diagram, I don't know if this way is possible, I hope you can help me achieve this requirement. I've used a statement like this in the picture in the command flow, but I can't save the stress contour diagram. However, I opened ansys APDL and imported the written command stream (.txt) text, which saved the stress contours

  Hi Yinzhong
  In Batch mode (the -b flag on the command line) there is no graphics window to capture. Instead use the /SHOW command to redirect a plot to a file:
  /eshape,1,,
  /show,png
  plnsol,s,eqv
  /show

    Thank you very much, I managed to save the picture, but it didn't meet my expectations, I want to be able to save the 3D model, not a line. That's how I modeled it .

  Looks like the /eshape,1 is missing

  The command I used was:
  /eshape,1,,
  
  /show,png
  
  plnsol,s,eqv
  
  /show
  I used the /eshape,1 command, and now I'm confused

  Hi Yinzhong
  Sorry, I forgot about the /GRAPHICS command! We need to change the graphics display as well to Power Graphics. So try:
  /post1
  set,last
  /graph,power
  /eshape,1
  /view,1,1,1,1
  eplot
  /show,png
  plnsol,s,eqv
  /show
  /rep
  finish

    Thank you, this way I open Mecheanical APDL Product Launcher, and then read the file I wrote in advance (.dat) can meet the requirements. But I use matlab invoking ansys (" s1 = "E: ANSYS2022ANSYSv221ansysbinwinx64ANSYS221. Exe - b - C: I UsersLYDesktoptesttxt write to override experimenttest01 (test).txt -o C:UsersLYDesktoptesttxt to write override experiment";) There are still problems. As you can see from the result file, the program will stop at this step (plnsol,s,eqv), and eventually the program will stop running. I wonder if there is something wrong with my ansys setup?
