  1. Hi, I want to create a solid mesh between two meshed surfaces, which will be shared surfaces to the solids they "belonged to" initially What I did so far: 0. Working in ABAQUS profile. 1. Automesh (Trias, elm size = 1.5) surfaces of interest 2. With Solid Map, I tried to make a solid mesh starting from the bottom surface, towards the upper surface, along a straight line (curve should also work, but I kept it simple for now). Problem: Bottom surface mesh is satisfactory. Upper surface mesh is 'double'/ not a shared surface and does not follow surface edge. Using the 'elm to match' option does not work, since this requires same amount of elms on both surfaces, which is not the case. Thanks in advance!
  2. Same problem here. Additionally, after checking free edges with Tools>edges, it says that there are no free edges.. So what now?...
  3. Thank you for your replies! Does the subdivision into many small domains affect the result after calculation? I have enclosed two images showing what I am working on, it IS necessary to have the same element density on the edge, right? and what about element density on the edge between two components, should these be exactly the same? (i.e. upper and lower vertebra?) Is this what they often call contact problems?
  4. Hi rdam, I have just started working in the FEA area, and I am trying to create a suitable mesh for a lumbar vertebra (L4) and in the end the L4-L5 motion segment (i.e. L4-intervertebral disc - L5). For this, I have created a 3D cad object from CT data and imported it as an iges file into hypermesh, where I surpressed all edges but one, and used automesh (only trias) to create a new 2D mesh. However, I want to have different element sizes for different parts due to computational efficiency that have the same element density where they 'meet' , any ideas on how to achieve this? Also, how do you mesh the difference between cortical and trabecular bone? Thanks in advance!
  5. Hi all, I am quite new to the entire FEA area, so I hope someone can help me. I have already worked through the entire HyperMesh tutorial, but I am still stuck. The problem addressed here is the kind of the problem I am facing as well. Working with an ABAQUS profile,I want to have a " smooth transition" (in terms of element density) between a coarse mesh (elm size, say, 6) and a fine mesh (elm size 1). If I use the replace function, does it matter if the elements become destroyed and/or deformed? Also, if I use 2D automesh with a somewhat larger element size, it seems impossible to follow the surface contours, what can I do about this?
