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




As you can see, there are interfaces in the fluid-interior. To correct this problem, I modified the end of file .msh :

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)) 
)) 
))

(45 (8 velocity-inlet inlet)()) 
(45 (9 pressure-outlet outletwater)()) 
))

And after I convert the file thanks to

fluentMeshToFoam file.msh

After that I modified boundary for my problem (after check patch name on paraview):

//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 :

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 .

Thank you
