Import geometry from AnsysMeshing with multi block
Good morning,
I have a problem maybe with the conversion of mesh. It is imported from Ansys Meshing.
Here is my mesh :

http://img11.hostingpics.net/pics/37...geboitier2.png
As you can see, there are interfaces in the fluid-interior. To correct this problem, I modified the end of file .msh :
Code:
b74b b7a2 b776 15d45 0
b72c b7a1 b799 1676e 0
b796 b7a2 b72f 15c90 0
))
(12 (2 1 4337d 1 2))
(45 (1 interior interior-solide)())
(45 (2 fluid solide)())
(45 (5 wall wall)())
(45 (6 symmetry symmetryplane)())
(45 (7 pressure-outlet outlet)())
(45 (8 velocity-inlet inlet)())
(45 (9 pressure-outlet outletwater)())
(45 (10 interface zone_de_contact-src)())
(45 (11 interface zone_de_contact-trg)())
(45 (12 interface zone_de_contact_2-src)())
(45 (13 interface zone_de_contact_2-trg)())
(45 (14 interface zone_de_contact_3-src)())
(45 (15 interface zone_de_contact_3-trg)())
(45 (16 interface zone_de_contact_4-src)())
(45 (17 interface zone_de_contact_4-trg)())
(0 Variables:)
(37 (
(sliding-interfaces (
(zone_de_contact(sb1-id 10) (sb2-id 11) (interior-id 0) (bnd1-id 0) (bnd2-id 0) (periodic . #f) (coupled . #f) (face-periodic . #f))
(zone_de_contact_2(sb1-id 12) (sb2-id 13) (interior-id 0) (bnd1-id 0) (bnd2-id 0) (periodic . #f) (coupled . #f) (face-periodic . #f))
(zone_de_contact_3(sb1-id 14) (sb2-id 15) (interior-id 0) (bnd1-id 0) (bnd2-id 0) (periodic . #f) (coupled . #f) (face-periodic . #f))
(zone_de_contact_4(sb1-id 16) (sb2-id 17) (interior-id 0) (bnd1-id 0) (bnd2-id 0) (periodic . #f) (coupled . #f) (face-periodic . #f))
))
))
by
Code:
b74b b7a2 b776 15d45 0
b72c b7a1 b799 1676e 0
b796 b7a2 b72f 15c90 0
))
(12 (2 1 4337d 1 2))
(45 (1 interior interior-solide)())
(45 (2 fluid solide)())
(45 (5 wall wall)())
(45 (6 symmetry symmetryplane)())
(45 (7 pressure-outlet outlet)())
(45 (8 velocity-inlet inlet)())
(45 (9 pressure-outlet outletwater)())
))
And after I convert the file thanks to
Code:
fluentMeshToFoam file.msh
After that I modified boundary for my problem (after check patch name on paraview):
Code:
//6
5
(
wall
{
type wall;
inGroups 1(wall);
nFaces 16430;
startFace 534639;
}
symmetryplane
{
type symmetryPlane;
inGroups 1(symmetryPlane);
nFaces 6198;
startFace 551069;
}
outlet
{
type patch;
nFaces 129;
startFace 557267;
}
inlet
{
type patch;
nFaces 129;
startFace 557396;
}
outletwater
{
type wall;
inGroups 1(wall);
nFaces 124;
startFace 557525;
}
// default_wall
// {
// type wall;
// inGroups 1(wall);
// nFaces 9012;
// startFace 557649;
// }
)
I checked and corrected the name of patch on every file in folder 0.
After that I ran simpleFoam and I have this message :

Erreur de segmentation (core dumped)
I don't know if the mistakes are from the importation of mesh or from the solving.
I already did a solving with the same geometry but with only one block and I didn't have problem.
Sorry for my English (I'm french). Please use easy words to answer :confused:.
Thank you |
