I'm currently working on a unit cell study (carbon fiber + matrix + additives). I thought it would be very easy to mesh it out and run my test, but I've been spending too much time in determining good quality of mesh. I have 3 components (3 different solids) that need to be meshed. I was able to successfully tetra-mesh individual solids with curvature and proximity, but couldn't find the way to somehow connect them. I tried to re-mesh multiple times with 2D automesh to tetra mesh technique, translating surface meshes to another, assigning equivelent on the duplicated nodes, etc. But frankly, it's too time consuming to accomplish good quality mesh, and I can't spend more time in this part. Later on I found the contact surface method preventing the penetration between parts by assigning slave and master BCs on shared surfaces (i.e. outter surface of carbon fiber and inner surface of matrix). Please give me some advice whether node connectivity can be replaced by assigning contact surface. My one concern is that later on I'll have to check the carbon fiber penetration in a reality scenario, and this method won't work for that due to the slave/matster bounded condition. If node connectivity must be properly done (which I assume..), please provide me some type of tutorials that present about connecting "multiple solids". I've went thru lot of meshing tutorials but only found the ones for single component/part or simple geometry setup that can be easily automeshed/translated/rotated.. Figure displays the carbon fiber (purple) and matrix (gray) nodes are not connected. Figure 2 displays the contact surface BCs applied on the shared surfaces of carbon fiber and matrix. Please excuse that I am not allowed to upload the model.. Your help would be really appreciated.
Hi, I have multiple solid components. For my Analysis, I'd like to connect some of the components in certain Areas, but not everywhere where the components "touch". In order to do that, I equivalenced some of the nodes of the two components, which works absolutely fine for my model. But: I would still like to have some of the solids' surfaces not to be connected with equivalenced nodes, but at the same time the surfaces (that are next to each other and in undefined contact) should not be able to penetrate each other during the nodal displacement of a static analysis. How can I create the option that a surface is defined as "not penetratable"? I tried different things, for example creating contact surfaces on each component. But that does not work as I thought it would. Could anyone help me, please? I would be happy to receive any kind of hint or short explanation. Thank you! Regards Hampel
Hi guys, i want to contact the red Shell component with the Grey solid. I´ve don this with the tool autocontact. The Problem is i want to delete parts of the green contact surfs, can someone tell me how. In the Pictures attached i marked the surfs i want to delete with a blue dot. Thanks for answering.
