Hi folks,
Kinda getting a hang of FEMAP but somehow finding it more frustrating than PATRAN (which is surprising). The demo videos posted by FEMAP is excellent and definitely help newbies with getting a foot in with the software.
Currently working on doing a local analysis of a cutout with fastener holes. It is important to get a clean good mapped mesh around the individual holes as well as around the cutout. I have attached a few pictures to illustrate my issues.
The geometry was imported as a Step files (would importing it in a native CAD format improve translation?). I am having issues with breaking down the surface before I mesh.
Image 2 illustrates the issue I had with offset. I was getting a discontinuous curves instead of a single one. Finally, I had to create a circle and trim it (tedious is what I felt).
Edit: I was able to join them using point to point option in geo edit (meshing tool box).
Image 3 illustrates the issue with curve splits and how I am unable to join them.
Image 4 illustrates the mesh I obtained after around 4 hours of work. There are still some trias in the critical zone which is undesirable for us (& the client). Hoping that experienced folks provide more insight in to perhaps easier ways of breaking down surfaces before meshing.
The images are clubbed together in a zip file. Sorry about that. Was not able to upload or attach more than one file to my post.
One more fact. I had to use mesh -> copy and/or reflect and/or rotate to obtain the mesh especially in the critical zone. I was unable to associate the mesh with curve/surface and hence when I meshed the surface outside of critical zone, it did not automatically retain the connectivity. I had to manually connect them and thus some trias sneaked in there. How can I ensure that association is maintained when I copy or reflect etc mesh.
Thanks in advance,
Regards,
