I guess you are then importing it in some standard geometry format (step, parasolid or iges) to DesignModeler. When you do so, make sure to mark it as "frozen" (in the import step) and keep your bodies in frozen (not "material") throughout your modeling - that's what I normally do (I'm working...

If you also tried to let a line body go through and joint'ed them (I assume you put them in one part first) and still there's no center point, that you can use to apply your force, first, it sounds very surprising to me, and second, let's try it another way: Cut the circle disc in four slices...

In Ansys Classic I would select that center node (I assume you mean the center of the circle disc?) graphically, by node number, or by location and apply the force using F, all, x, 1 Force of 1N (or unit) applied in x-dir, to all selected nodes (check the syntax, I'm writing it from my...

I have had very good results using the joint feature in DesignModeler (I basically stopped using Share Topology altogether when dealing with surfaces and lines) for line bodies and surface bodies to share nodes (thereby be connected) when meshed. When my lines were in-plane with a surface, they...

Hi Jact Actually, when I wrote "body" I meant specifically "body" in Ansys Workbench terminology. A body can be a line body, a surface body, or a solid body. I was assuming the body, on which you added the command, was a line body since you wanted to convert it to a Beam24 and I don't think...

Hi Biricio You have to make sure that you use the 1/4 force on each upstand compare to the force you put on the cylinder. I.e. if you put 15080 N on the cylinder you put 15080 N / 4 = 3770 N on EACH of the upstands. Or If you put 240 N on each upstand you should put 4 x 240 N = 960 N on the...

Hi Going to repeat what is written in this forum topic a few times. Have you tried adding a command to the line body you want to be a Beam24? Right click on the body in Workbench Mechanical -> add command -> write "et, matid, 24" (maybe matid can be replaced with an element type number of your...

Think the link doesn't work. But if you want to make an analysis without the cylinder (and only have the pressure on the cylinder) you have to work out what corresponding pressure to apply on the upstands. Guess you just scale up the pressure with the ratio between the big cylinder surface and...

Hi Not sure I understood it correct, but if you're interested in the displacement use Plnsol, u, sum For displacement vector sum, or Plnsol, u, x For displacement in x direction only. You can also "prnsol, u, sum" to get displacements printed to a text file. But maybe this is not what you're...

You, have to check the actual area of the cylinder where the 2 MPa is applied and then calculate the actual force - I just estimated the area. Also, as I said the constraints on the upstands will be slightly different, but otherwise the stress should be the same. Christian Hansen Twitter...

Two reasons: Reason 1) The force on the upstands are very different from Test1 to Test2, by far. Test1: You have 4 areas of approx. 5 mm X 5 mm = 0.0001 m2, with a pressure of 2 MPa -> total force of 200 N (check it!) Test2: You have 1 area of approx. area = Pi * r^2 = Pi * (50 mm)^2 = 0.0079...

Ok. It depends where you are interested in seeing the stress. It you are interested in the stress near the contact on the four upstands then I would add a piece of the cylinder and put force on the cylinder or alternatively put force only on contact part of the four upstands. If you only want...

In Ansys Classic: think the iges surfaces are defined as areas in Ansys Classic, if you give those areas attributes (material) and mesh you can get a mesh for your analysis, something similar can be done for the lines. If its a simple geometry I would probably re-model (or import the Iges...

As a start I would divide the force you are applying on the cylinder with the combined contact area of the four slabs you have between the cylinder and the plate. Unless you have other loads or constraints not mentioned here, this number would give you the stress on the plate exactly where the...

Hi ru263 Looked at your attached screen-dump from Ansys Mechanical - and you're close to the right place! Look at the section on the left side of the screen (I think Ansys names this space something like "Project Outline"), click on the "+" where there is a question mark and the word Geometry...

Hi Madbedger I assume it is a surface body and a solid (the cylinder), and that you are using "Shared topology" option? Solids can be a bit tricky, and I think you have to first slice the surface (e.g. using a surface from the cykinder) and suppress the part of the sheet that is contained...

Take a look at my answer here: http://eng-tips.com/viewthread.cfm?qid=319224 For the element type number you should not write, say Beam189, but write: et, 1, 189 You write it in Mechanical by right-clicking on each body (that you want to change element type for) and click Command/add comment...

Check out my answer in this post, I think you can export as Shell63 and force Workbench to use real constants: http://eng-tips.com/viewthread.cfm?qid=319224 The elements you are exporting now (for a ship - shell elements I assume?) does probably not have reals defined because Ansys is moving...

Hi As default Ansys Workbench export as Shell181 element type and uses section properties (real constants will soon be phased out as far as I know). I think actually that Shell181 can not use real constants to define thickness. What I did before when I wanted to export shell63 (an older shell...

Hi Mark Appreciate you reply here. My experience using translators embedded in commercial FEA programs is that they are 'of course' not perfect but they are still having errors in some elementary translations (like translating beam orientations and cross-sections, like translating shell...
