Hi,
Anyone else using matlabs live link with comsol and finding it slightly less robust then they would hope :).
For some reason calling ModelUtil.showProgress(true); will 40% of the time actually work and cause it to come up while the rest it fails to do anything.
Anyone know of any other commands that might be useful in bringing up the main Comsol window?
I need it up sadly because the solver can hang, generally at meshing, and therefore i need to cancel it.
Is this not a really silly way to go about it, I would have thought there might have been some way to cause it to time out and return null or something, kind of makes automated linking redundent.
Regards MF

Hi Michael,
I have the same issue. Could you find a solution? I already contacted Comsol support, but I am not able to create a reproducable example. If you have an example file where the progress window always does not show up, this could help to solve the issue. I use Comsol 4.2.0.187 together with Matlab R2010a on a WinXP platform.
Sunny regards,
Stefan

HI everyone,
Yes, I do have the same problem. I am using exacty the same matlab and comsol version as you Stefan. I would also be interseted if you can find a solution
Best Regards

Hi,
I might have find a way to make the progress bar appear more often. Even if Matlab was started using the 'COMSOL with Matlab' application, I start with the comand line mphstart before creating my model with 'model = ModelUtil.create('Model');' It should not be required since a server connection already exist but in my case the progress bar appeared all the time so far. But I haven't tested it for a long time so I cannot tell if it totally solve the problem. Let me know if it has helped you, so I will know if I only had chance or if I have to keep looking for a solution.
Best regards
Vincent

Hi guys,
has anyone in the meantime solved the issue or able to report it to Comsol? I probably got a reproducible case, so before contacting Comsol I'd like to know how's going with you.
BTW: I tried Vincent workaround but, at least in my case, does not work.

Hi Jacopo,
I can now confirm that my workaround does not work all the time. In my case it actually works better but nevertheless the progress bar does not appear in every situation. However I was not able to find out when it works and when not.
Let me know if the comsol support can help you on that one.
Regards
Vincent

Ok, perfect. I'm actually waiting for another support reply, still on Comsol w/ Matlab, and as soon as it is solved I'll submit this one.
I'll keep you updated...

Here is what the support says:
Dear Stefan,
Thank you for your detailed answer. I have used your M-file in order to reproduce this behavior. But I can see the progress bar each time I solve a problem, even if I do certain changes and/or restart MATLAB. I use MATLAB 2011a and Windows Vista.
Note that this kind of unexpected behavior can in several cases depend on the version you are using. In order to fully support this case, we ask you to upgrade your MATLAB version to one of the supported ones. Version 2010a is not officially supported by COMSOL 4.2. I would recommend you to try version 2011a instead (or 2010b).
Check with your colleague the MATLAB version he is using. If this problem appears in the supported versions of MATLAB, please let us know.
Best regards,
Pablo Vallejos

Ok, I'm gonna write them since I'm using both Matlab R2010b and R2011a and I can't see the progress bar...

In some cases the progress bar window is kind of "hidden". You have to minimize all other windows on the desktop to see the progress bar. (The progress bar does not have an extra item in the task bar.)
However, even when minimizing all other windows I can not always see a progress bar with R2010a.

Hi,
Sadly I have had no luck in solving this issue.
I can somewhat get arround it by having task manager up, this allows me in some way to tell whether the server has stalled, in which case I can close it and my program automatically restarts the process. At that point I cross my fingers and hope I get the progress bar :).
There almost needs to be a Bool on whether the progress bar is visibile, that way checking it and the ability to call it up seperately would be nice.

Hello,
Since I have the same problem I would be interested if there has been a solution to this problem.
Thanks,
Robert

Hi Robert,
in my case (running on Windows 7 and Mac) the task bar appears almost any time I call it. The only issue is that is covered by all the other windows; is there, but is hidden. Try to, if not already done, to have just the m-file window on the desktop and also have it really small, run the code and probably you would be able to see the task bar. Perhaps you have already tried so this post will not be of much help.
There is the new version now, v4.2a, perhaps in this version the task bar works smoothly.

I am having the same issue of the progress window not showing up most of the time.
In my case I am using comsol 4.2a with matlab 2011a on a 64 bit Linux machine.
Even when I set
ModelUtil.showProgress(true);
The progress bar does not show up most of the time.
It looks from the previous posts that there is no solution to this problem yet.

Well, we're seeing this as well with COMSOL43.
In the bowels of the .comsol directory, in a file called '.log', the following error is being thrown by COMSOL:
org.eclipse.swt.SWTException: Invalid thread access
at org.eclipse.swt.SWT.error(SWT.java:4282)
at org.eclipse.swt.SWT.error(SWT.java:4197)
at org.eclipse.swt.SWT.error(SWT.java:4168)
at org.eclipse.swt.widgets.Display.error(Display.java:1258)
at org.eclipse.swt.widgets.Display.checkDevice(Display.java:764)
at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3743)
at com.comsol.guimph.progress.ServerProgressHandler$a.run(Unknown Source)
It looks like COMSOL is having a threadng issue with the progress window accessing the screen.
