add github ci compile check for ascent

[cyrush]

Adds github ci check that complies WarpX with Ascent=ON, using an Ascent container.

From here we could run a small test, render, image and provide that image as an artifact.

[cyrush]

@ax3l i have the container build test for Ascent sorted out.

Do you suggest we also run a small test and render a pictured as part of the process, if so what test would you recommend?

[cyrush]

• Cyrus: Add newline to end of CI yaml file.

@cyrush awesome, thanks a lot!

We could use the 3D laser-wakefield (LWFA) test: https://github.com/ECP-WarpX/WarpX/blob/development/Examples/Physics_applications/laser_acceleration/inputs_3d and render out in a single scene:

• iso-contour of Ey (laser pulse)
• volume rendering of Ey (just to check it works)
• particle species: "electrons" colored by pz?

[cyrush]

@ax3l sounds like a plan, I will tackle that soon.

[cyrush]

I have the tests running :-)

I put the input deck and ascent actions file in .github/workflows/resources, not sure if this is a good place so please let me know if I should move elsewhere.

The setup also provides artifacts (pngs and blueprint files), you can see an example here:

Thanks a lot, that's fantastic!

Nice, I added some house-keeping updates in Alpine-DAV#1

The setup also provides artifacts

Awesome! For the Ey volume rendering, can you please set the color bar to be

• symmetric around zero and
• transparent for zero

? :)

[ax3l]

Ups, let's rename Examples/Physics_applications/laser_acceleration/inputs_3d_ascent_test_ascent_actions.yaml to Examples/Physics_applications/laser_acceleration/3d_ascent_actions.yaml or so :)

[cyrush]

@ax3l I updated the color table for the volume rendering example, here is the output (from the actions artifact)

Let me know if there are other tweaks we should make.

[ax3l]

@cyrush thanks a lot, awesome! Can we rotate the volume rendering figure by 90 degrees in the horizontal axis please? :)
(Positive z values to the right, if possible :) )

[cyrush]

@ax3l How do these look?

Note: For contour, the extents are different post contour - so that is why it looks different from the other two.

[ax3l]

Awesome! 🤩

Thanks a lot! 🚀 ✨
