Hey guys, In Hypermesh, under the Ansys User Profile; I cannot seem to figure out how to show shell thickness offsets. Example: 1. I apply a thickness of .5" to a Shell181 group of elements 2. I change the Section Property SECOFFSET optio to TOP / BOTTOM / USER instead of MID 3. Hypermesh still shows the thickness at the middle of the element. To parallel this, I know that the Nastran user profile will correctly display Nastran imposed ZOFFs applied to PSHELL cards. This is the desired affect I am looking for graphically in Hypermesh for the Ansys User Profile. Does anyone know how to view the thickness offsets applied with SECOFFSET in Ansys? Thank you, -aero
Hi, I've been provided with a hm model and need to carry out some geometry changes. However, the component I have been given is 3D tetrameshed without any surfaces. Is there anyway I can generate a surface from the provided tetra? I've tried using the surface from FE function but as I only have a 3D this wouldn't work. Thanks in advance, Tom
Hi all!! I have a question, which might seem quite obvious but it is driving me crazy. I am modelling honeycomb panels with 2D surfaces. Until now I have always modelled this material as 2D orthotropic, so with MAT8. Now my materials have changed and the following question arises to me: For the core ply, information available from manufacturer data sheets is the following: E3, G13 and G23. However, if I want to treat my model as surface, it is not possible with MAT8, because material parameters that I can introduce there are E1, E2; G12, G23, G13 and Poissons ratios. Is there any estimation or any conversion possible in order to make it work with shells? Another possibility is to model it with solids and using the Optistruct Engineering Solutions tool, which enables me to create a solid out of shells; however, when using it all contacts between surfaces are lost. Has someone faced the same problems when modelling honeycomb panels? It would be of great help. Thanks in advance!! Regards, Andrea
