Can't view my results in CFD-post ( AWS EC2 t2 instance )

I am using an academic student version of Ansys on a AWS EC2 t2 instance.

Reproducing a simple tuto, everything running well until CFD-POST stage.

There the view side of CFD-POST is only a black-screen.

I restarted everything twice, including Windows reboot, view side of CFD-POST remains a black-screen

I know AWS EC2 t2 instances are not built for graphical rendering performance, but my simulation is very simple, pure academic training, and any slow rendering would be sufficient.

I googled to search a way to configure CFD-POST to accept  AWS EC2 t2 instances, without success.

Please help if you use Ansys on AWS EC2.

To complete description, the "Save Picture" menu works well.

After 10 minutes of try and run, doing exports after every move in blind mode, I obtained a nice picture validating part of my tuto.

So, I confirm, only the view part of CFD-POST is broken.

But working in blind mode on black-screen is a mess, I cannot use it more than this check.

I found the way by myself, maybe very few people are using ansys on AWS


the Solution is => when you create your instance on AWS you have to add a "Elastic Graphics Accelerator"


it's a simple option in "Instance Details" of instance launch dialog
