I am trying isotropic adaptation of a 2D mesh to a solution field. The refined mesh itself looks good but a couple of boundary edges come out with an unreasonable reference value, 1701607982. The input mesh’s boundary edges have 1, 2, 16 or 32 as their reference values, though.
I am using the API functions for MMG2D but the same problem occurs when the input mesh and solution are given to the stand-alone executable, mmg2d_O3.
The input and output meshes and solutions are attached below for your reference:
input mesh: mmg2d_test.meshb (17.1 KB)
input solution: mmg2d_test.sol (4.7 KB)
output mesh: mmg2d_test_optimized.meshb (69.9 KB)
output solution: mmg2d_test_optimized.sol (21.2 KB)
