FEMAP: meshing a surface based on an other surface¦s mesh

FEMAP: meshing a surface based on an other surface¦s mesh

FEMAP: meshing a surface based on an other surface¦s mesh

(OP)
Hi!I think this is a fool question but i've trying hard and can't get what i'm looking for.
I've attached a picture. This is an imported assembly (Solid Edge). I've use midsurfaces commands and meshed with plate type elements. The meshed part is supported by a table. I want to mesh the table also with plate type element but different thickness. I want to make the table's nodes be conincident with the already generated mesh nodes. Is it possible? I want this meshes behave as if they were welded but i do not want to use conecctions, just using coincident nodes .
Thank you in advance for your help!

RE: FEMAP: meshing a surface based on an other surface¦s mesh

Hello!,
If what you want is to have the same elements in both the table and the other part, simply make an imprint in the surface of the table proyecting the curves of the other part and use the same divisions and you will have the same mesh. Later merge nodes and you are done!. FEMAP is really powerful in this sense.

Also you have command GEOMETRY > SURFACE > NonMANIFOLD-ADD that allows you to create ONE part with both the table and the oter component. You can prescribe different properties to the different surfaces, but you will have ONLY ONE CURVE in the intsersecction between surfaces, then NODE merging is done automatically at the meshing time, OK?.

This is the only command in FEMAP which allows you to create “Non-Manifold Solid Geometry”, an option in the Parasolid modeling kernel which creates “General Bodies” as opposed to regular solids (FEMAP solids) and sheet solids (FEMAP surfaces). The command allows you to Boolean Add sheet solids to one another, as well as add “sheet solids” to Parasolid “solids”. The “Non-Manifold Add Tolerance” may be adjusted in an attempt to have more solids and sheet solids combined into as few “general bodies” as possible. This tolerance can be used in a similar manner to the tolerance specified in the Geometry, Solid, Stitch command where geometry will actually be slightly altered in attempt to make “general bodies”. The Incremental Checking option will check the body is valid after each sheet solid or solid is added to the “general body”. If adding a sheet solid or solid causes the “general body” to become invalid, the command will revert one step to before the particular sheet solid or solid was added, then skip it and try to add the next one.



You can define complex mesh like in this example, all in FEMAP:



Best regards,
Blas.

If problems post your FEMAP model here and I will take a look to it.

Thank you for your answers! I got what i wanted. I merged coincident nodes as you told me. Here´s a picture of the result!.
I want you to know Blas i am learning a lot from you (forum and iberisa´s web page) and i am thankfull for what you do. Your answers are very complete!. I hope i have the chance to take the courses given by you sometime.
Saludos y gracias!
