How to do a proper 3D mesh

Hello dear all.

probably my next question is quite easy or even was already asked before.

I already searched for many ways but non of them work.

Look i have a simple tube but one end is covered, i am performing some compression analysis but i want to do a proper mesh.

Therefore, using the automatic tetra mesh was not the best one, and now i am trying to create a more decent mesh.

I want to do simple bricks or cubes in one part of the tube then of course those bricks must be placed or imprinted on one part of the covered tube. but i don't know how to do that because there is not connection on the meshes.

such tube with on end covered is composed of one single material

Let me tell you that i already tried to split the body into two and tried to mesh them but my problem persist.

Also i used the boolean in order to set a shared face for the two bodies.

By the way i am trying to avoid meshes with kind of wedge like radial meshes.

Plase take a look at the image

    working from your 'assembly' model you have 2 separate/distinct solids, you need to join them together to get the mesh continuity, you can boolean them together (combine with 'keep common interface') then the shared face should become yellow, indicating the split is shared between the parts

    Then I Split it into quarters as mine, and did mapped mesh, my modified HM is attached

    This should be easily achieved with mapped mesh, it may help to split the solids into quarters to help the mapping, can you share your HM file? I have attached a simple example of what I think you are trying to do

    Dear Paul

    Thank you very much for your reply.

    What you just did, is exactly what i was looking for.

    Please can you share the steps on how to achieve the same results.

    By the way i m attaching the *.hm files (one is the geometry without split and the other one is with the geometry split). Actually is the same geometry that you created.

    Note: those geometries can be created in hyperworks (i know that), but i am doing them in a separated CAD software, because later one the geometry is going to be quite complicated

    Dear Paul

    Thank you very much, now everything is easier.

    I already got my mesh.
