openTELEMAC The mathematically superior suite of solvers

I created an annular sector (default parameters) containing 55 points and then used the new uniform mesh covering algorithm to create a uniform mesh with edge length 0.0005.

The resulting mesh has 10,064,634 nodes and 13,185,150 elements and was created in 5 seconds on my laptop.



Kindly, Alan

On another test case:

• File > New > 2D Shape > Circle (use default values)
• T3 UNIFORM Mesh Covering over the circle: orientation angle = 0.0 and edge length = 0.05
• The circle has 32 points and a corrected mesh covering has 360 million nodes and 720 million elements.

Blue Kenue 3.13.0 - RC1 takes 65.3 minutes (and incorrectly adds duplicated nodes)

• while the next installer will NOT add duplicated nodes
• and will take only 1.6 minutes (a 40.8 X speedup) to complete

Kindly, Alan

Post #47503 also shows that the new algorithm is faster. In that case, a 2 X speedup is shown.

As of 1 Sept 2026, after repeating the experiment in post #47502 it was observed that a similar performance result was obtained. After all of the upgrades and fixes in the last 2 weeks, this is a good sign.

Marching on! Alan
