Hello,

I am working on a 3D model of a tyre, which consists of 8 flexible bodies which make up the tyre and rim. In SolidWorks (in which I developed the CAD of my model) I made sure to seperate each of these bodies. As it is a repetitive geometry, initially I am modelling a 1/17 model (as the tyre pattern is rotated 17 times about the Y-axis). In SpaceClaim, I have shared the topology (as I would like for the contacts to have the same mesh for all 17 "sections" of the tyre), and am now looking into imprinting the contact surfaces onto one another. However, when applying the tool not all faces are highlighted. I have increased the tolerance (up to 20mm, which is way too high), but this merely highlights different faces. It may be that all the sufaces I would like to imprint do not intersect, however, I doubt this as when making the CAD, I made sure that all the surfaces intersected.

Looks like you have used Share function. nAre you using imprint option?nCan you please check project option as well?.n

Yes, that is correct. By following the tutorial series on how to mest repeating geometries (https://www.youtube.com/watch?v=itbYd0LLDyk) the first step is to share the tolpology between all the surfaces, then imprint (which I have not yet applied due to the fact that with any tolerance, all the faces I need to imprint arent highlighted) . Once this is done, one applys mesh sizings. Thereafter, one goes back back into SpaceClaim, and using the rotating pattern tool you rotate the 1/17 section and do a few other little things. Finally, you go into ANSYS Mechanical and check that all the previously added mesh sizings are applied to the same geomerty (to ensure that each 1/17 section has the exact same geometry all around.nIdeally I would like to follow the method in the repeating geometries tutorial, however, I will look into the project tool and see if it does what I need it to.Nevertheless, do you have any idea why the imprint tool does'nt pick up some surfaces? Is it that the sufraces have to intersect?n

Below I have attached the image of what happens when I select the imprint tool. As you can see only certain edges and faces are highlighted. I would need all contacts between the various sufaces (whos topology has been shared) to imprinted onto one another, so that the mesh for the 1/17 model is exactly the same when it is rotated using the patern tool. The tolerance is set to the default of 0.1mm.nn
