    Combine - subtract work one way but not the other

    SW2014, W10, x64 So I have a sphere & a square cross section extrude, they are not merged. I cut the sphere from the box & that works. Now I try it the pther way around & nothing the combine toolbox stays open & nothing happens. See pic below.. Any clue what's going on here?

    Good embedded or dev board for computer vision?

    Have been using a Rasberry Pi 3 for a a computer vision project but the lag on the video playback from the camera is just too painful. I was wondering if anybody with any experience in this field could point me towards a decent development board or some other embedded solution. Ideally it...

    Building a mesh from an imported mesh - fill a cylinder?

    I have a thin walled cylinder the mesh for which is calculated else where (for arcane reasons that dont impinge on the thread :D ) If I import this into CAE how can I mesh the hollow inside the cylinder?

    How to add Beam cross section properties to imported mesh?

    I have a mesh that was imported from Abaqus but the beam cross section data is missing. As a result the structural model omits the beam elements. How do I access the beam cross section data in Ansys? I cant find any way to do it in the FE Modeler, Mechanical Model or Mesh modules so far

    Node numbering dsicrepancy?

    I have imported an *inp file created in FreeCAD into CAE. I then queried one of the elements to get the nodal connectivity but the element numbering is offset in CAE from th enumbering in the *.inp file, see pic. Anyone know why this would happen?

    Cant select elements or nodes in FE Modeller

    ANSYS 17.1 I have imported an Abaqus beam mesh via the FE Modeller component but I cant select any of the nodes or elements in the graphics window.

    Element numbering errors???

    I have a 2D shell mesh reconstructed from a *.ply file. When I verify the mesh I get 55% errors in the elements (CPS3). So I get a list of all the bad elements & reconstruct the mesh again with the nodes rearranged in the bad elements. Now down to just 16 bad elements (~1.5%). if node...

    Do finite elements have to be planar?

    Is it possible to define a non-planar element. For example the shell in the picture below...

    Unmovable spline handles!

    This just keeps happening & so far I havent found an explaination. I create a spline & activate the spline handles at the begining of the spline but they just wont move even if I remove all constraints, still they wont budge, see picture. This seems like a very basic operation yet I can not for...

    Mesh import issues

    I'm trying to import a mesh from an Abaqus *inp file. I manage to import via the FE Modeller but I get the error "(DP 0) The Model component in Finite Element Modeler requires user input before it can be updated. For instructions on how to address the cell in its current state, click the blue...

    Invalid "Assignment" > Geometry issue?

    I keep getting the Invalid "Assignment" error with the association Project>Model>Geometry>Geom>Geom\Surface. The surface itself is rather complex & originally from an STL. I have gone through all the fixing routines in Space Claim & the geometry as far as I can assess is valid with no overlaps...

    Visual Studio & usermat question...

    Can I use Visual Studio 2017 with user defined routines or am I tied to VS2012?

    Cant select nodes for boundary conditions

    I have cylinder & want to apply a fixed boundary condition to the bottom so I select the appropriate nodes... I click apply and get.... Any idea why my selection is being ignored?

    Are there other FE elements types beside the Usual?

    Besides tri, quad, tet & hex are there any other element that have been used in FE? Not bothered if they have been successful or not (probably not as I would have come across them by now I guess)

    ANSYS Workbench very unstable

    Win 10, x64, ANSYS AIM 17.1 First it was the Meshing module that kept freezing & now its exiting the Geometry module that freezes. I'm using the simplest geometry imaginable, a square! Anybody else have similar issues?

    Ansys AIM tutorials?

    HI I'm new to Ansys so I decided to workj through some tutorials they provide on YouTube but I cant find the files that they use. For instance in the very first "Getting Started" video they import some geometry that they just assume you have, which I dont. Anyone know where these files are...

    How to plot freq response function for a node?

    Hi, I've run a steady state & dynamic frequency analysis & am now trying to get the frequency response functions (FRF) for particular nodes. So far I have only been able to output accelerations & displacements for every node. As there close on 1/4 million nodes this isnt ideal. What am I...

    Import CSV or TXT point cloud file?

    I'm new to Inventor & the Autodesk products in general so please excuse my ignorance. I'm finding it frustratingly difficult to find a clear explaination on how to import point data in CSV or TXT format. I honestly thought this would be a simple procedure. Is ther a simple 'import' fuction...

    SW 2016 poor performance on Win 10

    Anybody else seeing shockley clunky performance with SW2016 & W10? Just upgraded machine, OS & SW from Win7 & SW2014 Gotta say SW2014 on a Win7 machine was far FAR superior perfomancewise. Smooth 3D navigation, no pauses between clicking icons & action being taken. Now I have to wait a second...

    Modal analysis outputs missing

    I did a modal analysis on one of my models & had access to to global outputs in CAE like Participation Factor & Effective Mass but now when I open the ODBs in CAE I can no linger find these variables. What am I missing? Is there some secret menu I cant see?
