Hi, I am looking to write a script to place pre-meshed bolts at the bolt holes of an existing bolted flange mesh, an example of which would be below: The bolt hole pattern will not always be a perfect crown, and therefore requires a more general approach Are there any pre-existing tools in Hypermesh that I can use in a tcl script to automate this process? I know hypermesh can find and fill holes, im just wondering if it can find the hole, and tell me the centroid. Or are there any other clever ways for finding the hole centroids based on logically downselecting through tcl scripts? Ultimately the crux is being able to find the centroid of the holes, I can manage the rest of the scripting. If anyone has any ideas that would be greatly appreciated! Thanks Tyler
I'm a relatively new user of Hypermesh v12.0 and have run into an issue when trying to use the 2D Automesh on a particular geometry. I am meshing an elliptical cylinder with interior stiffeners, i.e., frames, intercostals, etc. that are bolted together. I am modeling the vessel with 2D, first order elements and am modeling all fasteners and fastener holes. The problem that I run into is that the 2D automesher (including midsurface mesher) performs one of three operations: Failed surface mesh Meshes only around the holes (this is when I specify washers in the parameter/criteria files) Meshes over holes/cutouts that are below a certain diameter I've reworked and modified all parameters and criteria that I feel are relevant and even those that I feel are irrelevant. Further, when I perform topological cleanup and have the preprocessor locate and tag holes, it tags all holes except for those above a certain diameter (so Hypermesh is treating the larger and smaller cutouts differently). No matter what, I cannot mesh this structure and the direction that I feel I am taking now is non-intuitive and quite frankly arbitrary. Any guidance would be appreciated.
Hi all, I am writing a script to detect fillets in a geometry and defeature it. Right now i am using *separate_fillets command for fillet separation based on the given radius ranges (0-2, 2-4, 4-8, ....). But it is not giving a proper output. Some surfaces are missing in between and when i try to defeature, surfaces are getting destroyed. Is there any other command to detect/defeature fillets properly based on the given radius?
