Issue with MATLAB Code Accessing OptiSystem 22 Subsystem Canvas

[Jaime Romero Huedo]

Hello,

I have been working with a MATLAB script that successfully opened OptiSystem, accessed its document layout and canvas, and also retrieved a subsystem’s component along with its internal canvas.

With OptiSystem version 21, this code worked without any issues. However, after upgrading to version 22, I am now encountering an error.

Here is my MATLAB code:

% Create a COM server running OptiSystem
optsys = actxserver(‘optisystem.application’);

% Section looks for OptiSystem process and waits for it to start
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Execute the system command
taskToLookFor = ‘OptiSystemx64.exe’;
% Now make up the command line with the proper argument
% that will find only the process we are looking for.
commandLine = sprintf(‘tasklist /FI “IMAGENAME eq %s”‘, taskToLookFor);
% Now execute that command line and accept the result into “result”.
[status, result] = system(commandLine);
% Look for our program’s name in the result variable.
itIsRunning = strfind(lower(result), lower(taskToLookFor));
while isempty(itIsRunning)
[status, result] = system(commandLine);
itIsRunning = strfind(lower(result), lower(taskToLookFor));
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Open the OptiSystem file defined by the path
directory = strcat(pwd,’\PRUEBA_canva.osd’);
optsys.Open(directory);

Document = optsys.GetActiveDocument;
LayoutMngr = Document.GetLayoutMgr;
CurrentLyt = LayoutMngr.GetCurrentLayout;
Canvas = CurrentLyt.GetCurrentCanvas;

% Here I retrieve the object, which is a subsystem
TransmiterCanvas = Canvas.GetComponentByName(‘TRANSMITER’);

% However, when I try to get its canvas to access its internal components, I get this error:
Canvas2 = TransmiterCanvas.GetCanvas;

Error Message:
Error using Interface.F1099F9F_9EE0_4649_899E_EBCF6BDB358A/GetCanvas
Error: The server threw an exception.

Error in SIMULACIONES_PM_con_ED (line 34)
Canvas2 = TransmiterCanvas.GetCanvas;

As I mentioned, this exact same code worked perfectly in the previous version (21), but now with version 22, it no longer works.

I would like to understand what has changed in version 22 that is causing this issue. Is there a new way to access the canvas of a subsystem in the updated API?

Thank you for your help.

Hello Jaime,

I have setup a test design file in OptiSystem and have tested it with your copied Matlab code. The script runs without error and I am unable to reproduce your error. If you could send an email to support@optiwave.com with the following information we will try to see if we can identify the issue:

• Are you using a paid version of the product or using the 30-day evaluation? If a paid version can you please provide your license number.
• Windows OS version – 10 or 11?
• Full version number of OptiSystem can be obtained from the “About OptiSystem” option under the “Help” menu. I am looking for something like 22.0..0.3239
• The “.osd” file you are using along with the matlab snippet.

Thanks,
Scott
