Currently failing longtests and examples

[tmbgreaves]

This issue documents the remaining failing tests following the Actions/GCC10 PR work. I'll update this initial post with the latest details - feel free to edit if you have updates, or note in the discussion below.

There are currently six failing tests/examples needing attention:

• EXAMPLE: driven_cavity : One failure, see note below
• EXAMPLE: lock_exchange : 'TypeError: only integer scalar arrays can be converted to a scalar index' [0]
• LONGTEST: lock_exchange_3d_parallel : 'Error: Process completed with exit code 137.' [1]
• LONGTEST: saltfinger2d_adaptive : GMSH erroring during mesh generation
• VLONGTEST: backward_facing_step_2d_longtest : Two testing failures, see below.
• VLONGTEST: flredecomp_long : timing out after three days, needs rerunning manually.

VLong tests are running on the longtests repo at https://github.com/FluidityProject/longtests/actions

Question moved from PR #311

@angus-g - I think I have a question for you: it looks like some of the examples / longtests which parse detectors are failing as a result of detector files now outputting as h5part, but the examples/tests are still configured to read old-style detectors output via stat_parse from the fluidity_tools module. On a first pass, tests which I suspect are failing from this are:

• wetting_and_drying_balzano1_dg_parallel
• hokkaido-nansei-oki_tsunami
• lock_exchange_2d_Lagrangian_paths
• square-convection-1e6
• Stokes_subduction_zone_vanKeken2008_OneA

Does this sound like it could be a reasonable diagnosis and if so how straightforward would a fix be?

UPDATED 2021/05/06 @jhill1 - I think I've now fixed the medp1dgp2 utScan bug.

Question moved from PR #311

@matt-piggott - I'm seeing what I hope is a marginal test failure in the driven_cavity example on Ubuntu 20.04, where a test of convergence > 1.85 fails on:

driven_cavity: Running Quantity4ConvergesToSecondOrder:
[[1.72761663]
[2.23112378]
[2.61936127]]
driven_cavity: failure.

Can this be relaxed slightly?

@drhodrid - a follow-up on the updated particle tests, I don't think I've messed up the merge of your updates but am seeing what looks like a significant RMS error change from particle_entrainment_of_dense_layer, see:

https://github.com/FluidityProject/fluidity/runs/2509562204?check_suite_focus=true

Test is '560 +- 10', actual value is 90.25800673280742

[tmbgreaves]

@drhodrid - in particle_rayleigh_taylor_mu10fold on Focal I'm seeing one failure of 'Max entrainment less than 0.9' but a test value of 'Max Entrainment 0.903234453893775'. Am I OK to relax that slightly to get a pass?

Hi Tim. I just pushed some changes that will hopefully fix particle_entrainment_of_dense_layer. Please let me know if that's the case when its run through.

[tmbgreaves]

Thanks Rhod, that's running now. I'll post results as they come in.

Update: test has run for significantly longer this time, which looks promising.

[drhodrid]

Ahhh damn! Back on my list for next week then!!

@drhodrid - this time was my error I think - sorry! I was running the previous version by mistake. But it still needs testing as it overran the 6h time limit on the standard queue, so I'm rerunning on the vlong queue now and will update with results.

[drhodrid]

Thanks Tim. If it passes, I can probably improve efficiency somewhat to get it under 6 hours.

@drhodrid - confirming pass: https://github.com/FluidityProject/longtests/actions/runs/849706302

Could I also nudge you on the hopefully-tolerance failure in particle_rayleigh_taylor_mu10fold ? I'm seeing one failure of 'Max entrainment less than 0.9' but a test value of 'Max Entrainment 0.903234453893775'. Am I OK to relax that slightly to get a pass?
