Hi,
In ANSYS you can import material properties of piezo ceramics. But where can I find the specific material properties that are required by ANSYS?
You can find all kind of piezoelectric material properties on the net, like...

I get the following error in ANSYS Workbench when doing a flexible dynamics simulation:
*** ERROR *** CP = 2183.203 TIME= 22:50:21
Number of results on results file exceeds maximum of 1000.
Maximum may be increased with /CONFIG command.

Hi,
I'm using different methods in the flexible dynamics of ANSYS workbench to obtain a movement of a plate (that is clamped on one side and free on the other side, see: http://img12.imageshack.us/img12/6376/1604200925507.jpg ) in the first bending mode, by:
1) applying a pressure on one side...
Hi,
Is it possible to obtain a voltage phase difference between 2 electrodes (areas) with ANSYS?
I have 2 (piezo) patches and in total 4 areas to apply a voltage. If I apply 0volt on one area, and 100 volt on the other area, I can apply the wished 100Volt on one patch. The same can be done...
Hi,
Does anybody know thin and light but stiff materials that could be used for wing material for the development of insect-like micro aerial vehihicles.
The price is not very important, however it is prefered that international suppliers can ship it (to Europe).
Any suggestions are very...
Hi,
I have made a parametric model of ANSYS Batch (in APDL). The parameters are defined in the beginning, and every paramater can be changed with MATLAB and the results of ANSYS will be saved (in txt) and read in MATLAB. After that MATLAB can rechange a parameter and let ANSYS run again, etc...
Hi
I have a plate made of a certain material (plastic, cannot be changed). I need to maximize the first resonance frequency of the plate. The availible methods are: making some places thinner and using ribs.
When using ribs on the plate with fixed dimensions (100mm x 75mm x 2mm) you can't...
It seems that ANSYS isnt fully compatible with Vista. When I do a modal analysis in ANSYS and try to write the results to a txt it seems to work just fine in XP, but in Vista I always get an empty file.

Hi,
I have made a small basic motor in inventor. I have constrained the drawings in a way that the motor runs correctly, however there is one error. The cams on the camshaft need to push up a shaft that is connected with the valves. Is there a possible way to let the cams push the valve up and...
Hi,
When I make a complex volume with keypoints, I do this by creating sub volumes, and use the VADD command to merge the volumes into one volume. In the help file is written that the original volumes (and their corresponding areas, lines and keypoints) will be deleted.
The problem is that...
I'm trying to select certain nodes on a plane, which is a part of another plane.
BATCH:
NSEL,S,LOC,Z,h_b/2+h_p ! Selects the desired plane [WORKS OK]
D,all,VOLT,0
NSEL,S,LOC,Z,-h_b/2-h_p ! Selects the desired plane [WORKS OK]
D,all,VOLT,0
NSEL,S,LOC,Z,h_b/2 ! Selects the desired plane...
Hi,
I have a batch file where the nodes on an area must be coupled. This can be done by using the picking operation (GUI). However this is dependant on the meshsize (increase of nodes), and on the geometry of the system.
When I avoid using the GUI picking operation, and use NSEL it works fine...
Hi,
I'm trying to select all nodes of an area that is defined. I can't use nsel (because ANSYS crashes then), I must use FITEM commands.
Example (from another work):
! Defining that the nodes on upper electrodes are coupeld considering the voltage.
! ANSYS crashed when the more easy command...
Hi,
I'm working on a project where very thin metal plates are needed to obtain the optimal results. The sheets of metal must be as thin as possible.
Does somebody know a company that can deliver extremely thin sheets of metals (stainless steel, aluminium, phosphor bronze, brass). The sheets...
Hi,
I hope somebody can help me.
I have modelled a beam (3D), and I want to test the influence of clamping by connecting the nodes to other nodes with spring elements. By changing the K of the springs the influence of the clamping could be tested. However I have a problem making the elements...
When one clamps an area in the real world it is not perfectly clamped like it is defined in Finite Element Software.
So I tried to test out what the influence of clamping was, in ANSYS. I had an idea to connect every node on the area of the clamping with springs. The springs would have a high...
Hi,
In the literature one can find only limited piezoelectric properties.
d31, d33 are most of the time given. How can one determine the other dielectric coefficients?
And how can one make the stiffness matrix out of that?
And how can one determine the relative permittivity in 3 directions...
Hi,
I have modelled a system in ANSYS Multiphysics where I do a harmonic response analysis. Note that I use ANSYS in BATCH. I have defined a point (Z1) where I want to list the Frequency, Amplitude and Phase (default). This is how the harmonic analysis in BATCH is defined:
