Hi, I've got a very thin plate. It must be piezoelectric, which limits the number of elements I can use to mesh it. I'm having a lot of trouble meshing it and getting an analysis to run. The code I've pasted below gives warnings, and then calculates deflections of 0 everywhere after I apply...

The two layers are different materials, so I have to mesh them separately. Do i do use vglue before or after meshing? I tried doing it before, and found that I got errors when I tried to mesh them separately afterwards. Greg

Hi, I have a beam that has two layers. I make each layer using the "block" command so that one is on top of the other. When I apply forces or do a modal analysis, can I assume that the two layers are stuck together, and they'll behave as one single beam? Or do I need to do something to make...

I have the following model that I want to mesh. I have a rectangular silicon membrane with a thin film of piezoelectric material on the front and the back. I'm having a lot of trouble meshing the two piezoelectric thin films. Everything I've tried gives me lots of warnings about bad mesh...

Hi, I've got a simple SimMechanics problem. I have a body connected to a revolute actuator. I'm applying a constant angular acceleration to the joint using a joint actuator, then I am measuring the actual angular acceleration of the joint using a joint sensor. It turns out that the applied...

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...

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...

Hi, I have a piezoelectric problem I'm trying to solve. I have a square plate on which I am applying oscillating forces. I defined the electrodes to be the top and bottom of the plate, and the bottom electrode is set to 0 Volt. So far, I can plot the electric potential of the top electrode vs...

Hi, I want to apply a sinusoidal load to a plate for a transient analysis. I know how to apply a constant load, but how do I vary the load over time? I'm an Ansys beginner, so thanks for the help. Greg
