Re: Running and monitoring simulations from home

When I say bursts of activity means I may only use CFD a few days per month, but often I need the results fairly quickly.

 

Regarding aggregating of messages, I wouldn't want them more than say every 15-30 minutes, but wouldn't want to wait much longer than that in case something needs fixing.

 

Regarding specific contact methods, I hadn't even thought about the smartphone app.  That could kill a lot of birds with one stone, especially since the IT folks are already dealing with those as inevitable.  The only stumbling block would be bandwidth-intensive interactions for debugging purposes.  I almost exculsively use cut planes for that purpose, so maybe one or summary plane snapshots could be sent or requested?

 

The other thing which would be really useful in some cases (actually in-person as well as remotely) would be the ability to monitor predefined derived quantities such as total flow through an inlet, pressure drop between 2 points, lift or drag force over a defined set of surfaces, etc. *during* rather than after the solution.  Like monitor/summary points, but much more powerful. Being able to see these values change would let me know if things are going in the right direction or wandering off much better than just convergence plots.

One thing I would like to bring up to see if this fills in most of a users need or at least drive conversation to specifics.  In CFD 2013 we now have the ability to send the convergence plot image (average plot only) at specific intervals which can give you an idea on stability and at the end of the run we can also attach the summary file and status file to review.  Do you feel comfortable with those to fill your need or would being able to define maybe a few static images of results that could also be sent over useful as well?  

 

I see the notifications as a way to be comfortable that when you come in on Monday you have something to work with.  If the model fails you learn that from the notifications and that might spark you to get on VPN/drive into work to fix the model and start again.

 

Personally, I think if you were running multiple scenarios AND had decision center features like parts, planes, etc. Maybe some of those can be sent with the notifications as well.  One issue with this is that if you did dynamic images the file size gets very large. In this case these could be uploaded to your autodesk 360 account automatically to be downloaded and viewed anywhere.

It sounds like 2013 implementation will provide very useful remote status updates.  I'm looking forward to getting it up and running!

Hello, I do it backwards... I run CFD on my Home PC while traveling to various offices. It is a BIG home PC. I simply use GOTOMYPC to connect from anywhere (even while on a cruseship) and it works great. I set the Notifications to text my phone as the solver progresses.

 

I keep the solid models (Solidworks) on my laptop so I can modify the geometry... create a parasolid (much smaller model) and transfer the model via GOTOMYPC. My models are relativly complex centrifugal pumps but this method works well for me.

 

By the way, it is cheap... about $20 per month.

We have a dedicated server machine with only the CFD software installed.  I can access this through VPN from anywhere I have an interenet connection via Window's Desktop Sharing.  I simply copy a .SAT file from my 3D cad software to the server then do everything remotely.  This way I can log in or out of the running server whenever I want to check the status.  This has been a lifesaver when I expect to have a solution for a presentation on the following day; if I check in and see a mesh or solve error, I can correct the cad model on my laptop, upload it, and run it again.

It would be helpful if the files attached to the notification email had .txt exensions added. My android mail program does not know how to display the .st and .sum files.

Good observation on the extensions.  Can you associate new extensions to programs in an android/iOS to something new like you can in windows?

 

Maybe it is time to consider changing the file name format to something like 'design name' + 'scenario name' _summary.txt, 'design name' + 'scenario name' _status.txt, etc.

 

Just a thought.

I use a dedicated cfd/fem solver computer with maximum power available for a reasonable price. I use GotoMyPC to monitor from where I can and create presentations remotely and synch to my laptop that goes with me.

 

Works well from all over the world.

The reason I have to monitor regularly is because the solver will "Exit unexpectedly" and there is no way to know why. Sometimes a restart from the last saved step works and sometimes not. I typically have large models (>10M nodes) that run for many hours to converge.

 

I connect to make sure it is working.
