[snappyHexMesh] Ship hull using snappyHexMesh

nuovodna · August 27, 2010, 06:52

Hi, i made a mesh around a ship hull using snappyHexMesh. The "checkMesh" returns me a warning on 2 non-orthogonal faces (with checkMesh on 1.6 i had no warning). I started the simulation but it fails with a Floating point exception error. Have you any idea??

This is the case

Is it possible to use this combination of applications for free surface calculation :

blockMesh
refineMesh (only in Z-direction)
snappyHexMesh

When I launch sHM i get the following error message:
--> FOAM FATAL ERROR:
cell 72260 of level 0 uses more than 8 points of equal or lower level
Points so far:8(74396 74397 74497 74498 79547 79548 79648 79649)

Regards,

Stephane
