Hello,
I examine a manometric membrane by using the Static Structural Analysis of Ansys Workbench. The analysis is done via the Quadratic Tetrahedron element by default. The major point is whether this element could be replaced with Shell41 and how it could be done with Workbench. I have attached a picture of the membrane. - http://files.engineering.com/getfile.aspx?folder=ec763221-9339-4319-8a7f-de

You need to define the mid plane and mesh that with shells. You will need DesignModeler to do this unless you do it in CAD. Chris

Hello,
I don't know how to define mid plane of this detail. I constructed the manometric membrane as Surface Bodies, the CAD element was created through the command Revolve of Autodesk Inventor 2010. How can I define the thickness of the membrane in the Static Structural Analysis of Ansys Workbench? Whiсh command must be used? 字串1
Thank you in advance.

You need to purchase ANSYS DesignModeler which will create a mid plane from a solid. Alternatively you can model a mid plane surface in cad and mesh that. A quick and dirty way of doing it is to mesh the outer surface of your part with shells but this won't be a true representation of the geometry. It may be ok for a quick look see though. Chris

Hello,
I put the mid plane by using the ANSYS DesignModeler in a CAD model of the manometric membraneна. I put Mesh on a CAD model иand the elemant type changed to 4 Node Linear Triangular Shell. Can I change it, I mean to be Shell 281 or Shell 41 and how can I do it? I want to make an analysis of the characteristics of pressure - deformation in the Static Structural Analysis of Ansys Workbench of the manometric membrane and I don't know how much precise the analysis with the element 4 Node Linear Triangular Shell is. Is there any solution for deflection in the Static Structural Analysis of Ansys Workbench? 字串4
Thank you for the help - http://files.engineering.com/getfile.aspx?folder=53e6e4a9-df43-418e-8738-70

You could try bringing it into ANSYS classic to do the meshing then bring it back into workbench. Chris

How do I have to do it because I tried but there was no result?

Why not do it all in ANSYS classic it will be easier. Chris
