Hi

I have so to say never neded to use the recovery feature (that does not mean that COMSOL does not crash time to time also for me ;) . But there is a File Open Recovery, have you tried that ?

On the other side most mph files are zipped ascii and binary xml files, but I have never seen the info about it's internal structure

Thanks Ivar.

Yes, i tried open recovery file menu but it doesn't give me the last saved model on my desktop.

On linux cluster, i am running comsol in batch mode and all i get is the recovery folder with no .mph files but .mphbin files for mesh, solution, geom etc. The data is there and the size of sol1.mphbin increases dynamically as solver moves on but in the end, i can not extract the .mph models.

I will try few other things and post back, if i am successful. Thanks again for your reply.

The time/date on the recovery file menu is a little misleading. To find the actual time stamp of the last saved iteration/time step, you go look at the last-written file in the recover-file directory. When you know which recovery-file you want (probably the latest), then open that recovery "record". If it is an blank empty work space, the name of the model will be untitled.mph. At this point, you can verify what is there by plotting results, etc. Then just save-as just like you normally might save a model file to a different name. You now have your .mph file with all data recovered.

I do this routinely when I want need to actually manually kill a long-running job, but want to recovery what I can. It works well.

Thanks James. It would be very useful but i guess this is for windows system where i can access they 'open recovery files' from the 'file menu'.

I am unable to figure about how to extract data from the last saved recovery file on linux cluster.

Thanks for your reply.

Windows ? Not here. I am an exclusive Linux user (until I absolutely have to run windows which is rare these days).

Step 1. left click "file" in the upper left-hand corner of the COMSOL menu buttons.

Step 2. left click "open recovery file" (the third item down).

Step 3. left click the latest time step recovery file in the list; COMSOL reads in the data

Step 4. do what you want to this model (view, change, etc.)

Step 5. left click "file" again

Step 6. left click "save-as" (fifth item down the list)

Step 7 . well, I assume you can handle it from here.

If you don't have a file listed in Step 2, you have not set the preferences to save recovery files. Do that before you run a job.

Thanks James for detailed instructions. I will try that and hope it will work.

Thanks again.

I have a similar problem..I find the recovery file saved in the recovery folder...but that file (latest saved) does not show up in the open recovery file menu. I am using windows.

Ok figured it out...Like Ivar said the date stamp is all messed up! The date shown in the name and the date actually saved are not the same...

Hi Mranal,

I encountered the same issue that I can locate the recovery file folder with multiple files as you showed in the pictures but it doesn't show in my "Open recovery file" list.
I am wondering did you figure out how to extract those files from the folder, if so, do you remember how you manage it.

Thanks in advance.

Hi Yi,

If you can see the files in the folder then all you have to do is go into the C:/User/username/.comsol/version folder and edit the comsol.recoveries file. If you open it with notepad, just copy the location of the recovery file you are trying to open and paste it in the file. Then save the file. Open COMSOL GUI back up and go to the recovery feature and you should see the file that you want to open.

Hopefully this helps,
Martin
