Meshing a plate

[gregthomas]

Hi,

I'm trying to mesh a piezoelectric plate. So far this is what I'm using:

block,0,800e-6,0,10e-6,0,1000e-6
et,1,SOLID226,1001 ! 3-D coupled-field brick
esize,,4
mat,1
vmesh,1

This gives me the warning:
"Shape testing revealed that 64 of the 64 new or modified elements violate shape warning limits. To review test results, please see the output file or issue the CHECK command."

I want to use a small number of elements (<50 preferably) to mesh my plate. Can anyone suggest how I can mesh it properly?

Thanks,
Greg

Hi,

If you want only 50 elements, then you should use shell elements instead of solids. The Plate you are trying to model is very thin and the solids would have with this esize a too big aspect ratio.

What's a piezoelectric shell element I can use then? These are the possible ones, which is appropriate?

PLANE13, KEYOPT(1) = 7 coupled-field quadrilateral solid
SOLID5, KEYOPT(1) = 0 or 3 coupled-field brick
SOLID98, KEYOPT(1) = 0 or 3 coupled-field tetrahedron
PLANE223, KEYOPT(1) = 1001, coupled-field 8-node quadrilateral
SOLID226, KEYOPT(1) = 1001, coupled-field 20-node brick
SOLID227, KEYOPT(1) = 1001, coupled-field 10-node tetrahedron

Thanks for the help! I'm just a beginner.
