Hi, I hope I do not bother anyone with questions to which answers might be obvious to advanced users. Using Hyperworks 11, I'd like to create a simple adhesive contact in Hypermesh between two solid compontents, hex mesh. The tutorial HM-3410: "Creating Area Connectors" only treats 2D-elements and doesn't work the same way for 3D-elements. Could anyone give me a short hint how to "glue" two compontens together, please? I would appreciate it very much. Have a nice day Hampel
Hi, everyone. I encountered a problem when I reflected a model with area connectors. The model is symmetric, but the whole model must be analyzed in some cases. I reflected the original half model (half model.hm) about xz plane of AxisSystem1 (ID=1) by using *duplicateentities and *reflectmarkwithoption and *equivalence commands, then merged the same components and load collectors. However, the analysis of the symmetry model (symmetry.hm ) cannot be executed properly and gives too much errors such as, *** See next message about line 47237 from file: E:/HyperWorks_Work/Symmetry/Symmetry.fem "RBE3 26648 23617 0 22003 23619 23620 23621" This line was interpreted as: 47237:RBE3, 26648, , 23617, 0, 22003, 23619, 23620, 23621 *** ERROR # 1000 *** in the input data: Incorrect data in field # 5.

Expected COMPONENT numbers, found INTEGER (0). . . . The errors in .out file reflect that the RBE3 elements in the reflected Glue component have wrong information. The RBE3 elements seem not to be reflected properly. BTW, the half model can be analyzed normally. I don't know where the problem is. Can anybody gives me some advices? Thanks. half model.hm Symmetry.hm Symmetry.out
Dear Members, my problem is the following: I want to calculate the frequency modes of a gearbox-housing that consists of two parts screwed with a flange, using OptiStruct as solver. A validated approach that I want to try is modelling the screws as a bar-element that connects two mpc-rigids, one in the thread-area an the other in the area of the screw-head. The problem that I have is the connection of the two meshes (3D-parabolic with tetra-elements) of the parts in the flange-area. Simply connecting the whole flange leads to unsatisfactory results so that I just want to connect the flange areas in a certain radius auround the axis of the screw. My first idea was using the area-connector to create rigid-elements, but I still have problems to understand, how it works and if its even possible to do it in that manner. When I select "elems" in the location-botton of the area-panel and "rigid" as type no area-connectors are created independent of every other option chosen. Using "node list" leads to really strange connections and its hardly possible to even achieve a creation of some connections. Does anyone have an indea of a different approach connecting the flange-areas? As far as I know defining a contact is not possible for a modal analysis due to linearity. Thank you very much in advance!!
