Femap

Femap

(OP)
Hello everybody !

I would like to know how I can manually move nodes in femap in order to get a better mesh and also how i can paste nodes.

Moreover, i'd like to know if there is a powerful tool to automatically improve a mesh (like the recons in ansa for example).

Thank you for your answers.

RE: Femap

You can project nodes onto curves, surfaces, or vectors or along vectors using the Modify/Project command. You can move nodes to points using the Modify/Move to commands. To automatically improve a mesh you can use the Mesh/Smooth command. There are also a number of mesh editing tools under the Mesh menu for things like splitting elements, etc. One irritating factor, particularly with the Move node command is that you have to select the tool for each node you want to move. A good way to make this less irritating is to right click on the screen and select the "previous command" option.

The tools in the meshing toolbox are also VERY helpful, particularly the mesh sizing tools. Preparing your geometry before meshing is very important to obtaining a good mesh. The tools in the Geometry Editing and Feature Editing menus of the meshing toolbox are very handy for this. I would suggest you play around with the tools to see what's available and what works for you. FEMAP is a very powerful pre-processor once you learn to use it. It's much more intuitive than PATRAN, which I used for several years before encountering FEMAP.

I hope this helps.

RE: Femap

1) use more informative thread headings pls, for this one something like "moving/relocating nodes"

2) as above there are several ways to do what you want ...
a) modify/edit/node ... allows you to reposition a node,
b) i'm pretty certain you can embed a node into the mesh, something like mesh/mesh control/mesh points on surface,
c) under mesh/editting you can easily remesh surfaces (loads applied, like pressure, are correctly refined),
d) under mesh/refine you can remesh beams (be aware that this will "mess" loads applied to the beams),

3) get some training, read the manuals, ask the help desk
