Femap - meshing
Femap - meshing
(OP)
Hello,
I have part with 600*300*10 mm. I need atleast 3 layers of elements thru 10mm thickness and same time less no of elements on other surfaces. Global meshing produces very fine mesh on every area.
What should be my approach? I am new to femap.
Thanks,
feaplastic.

I have to use hyperelastic material with large deformation. So, Plate element is not usable. My part is pretty complex with ups and downs than i explained in my OP. So, It is not possible to copy from outer or midsurface.
One method i found was, mesh all outer surfaces with polt only elements as required and create solid mesh using plot only elements. It worked fine for simple model. Even it has mesh propagation density control. Is it a right method or Any other idea?
Thanks for your replies.

But 10mm thick and 3 elements will will give you a very high aspect ratio och a huge model considering the other dimensions. I would try to convert the 3d material model to a 2d model. If one dimension is much smaller tanh the other you usually have a plate.
Good Luck

I use Abaqus and already tried to model with shell element. It gives a error msg straightaway.
Thanks,

sorry for the confusion. Preprocessor is femap and analysis is in abaqus. Abaqus says i could not use shell element for hayperelastic model. Is it possible in Nastran?
Thanks,

I'm sure there are others prepared to give an opinion that know a great deal more about the specifics of other packages.
RE: Femap - meshing
What version of Abaqus, what shell element type, and what material model were you using, and what error message did you get?
I'm not seeing any errors in my test here (Abaqus V6.6, S4R elements, Neo Hooke hyperelastic material based on test data, NLGEOM=ON)
