    How many elements/nodes is too much to handle?

    I have a question: were I to have a multi-core processor, would ANSYS make use of all of them or would it run on one core only? would a distributed processing licence be needed?

    Solid92

    Some loose thought: - What is defined in the .tet file? Is it a mesh, volumes, surfaces, combination of the three? - Why you trying to mesh areas with solid elements? That would result in the error you reported. - Looking at the lines of the AMIRA output file there's a line, "et,1,solid92"...

    mesh control

    Have you tried creating one or more components out of the areas (for example) that belongs to the holes you are making? Knowing the location of the holes, you can select the areas by location (switching to a polar coordinate system centered on the hole center and selecting every area between r-x...

    FK, DK and smrtsize

    Could you provide us with the batch file you are working on? As long as I can understand, there isn't really any need to issue FTRANS and SBCTRANS as they will be automatically issued once you issue the SOLVE command - but I guess you have something more in mind? If you create a node by...

    Difficulties importing IGS-files

    As long as my experience goes, you better forget about IGS - the end result is not worth the pain as long as you have better ways to import your model - importing Catia V5 parts always worked like a charm with me - I'm sorry I can't be of any help with your problems there.

    Radiation problem

    There are some corrections to make to your code: 1) the surface element you should use for radiation analysis is SHELL57 (as recommended by the manual), not SURF152. By the manual it seems that SURF152 can be used too, but not as easily in the AIX12 (read the SURF152 manual entry for more...

    can I calculate the memory requirements for Sparse/Direct solver?

    Just wondering if it wouldn't be a help switching to other elements for your model, if it's correct that your model is meshed with SOLID186. That is a 20-node brick element, but by looking at the picture of your spline I surmise it's meshed with tetrahedra - I guess it could be worthy changing...

    STEP importation problem

    Thanks DBezaire for the hint, I'll check it ASAP. Regarding the move XP and R16, unfortunately I can (and will) only suggest it, not enforce it.

    STEP importation problem

    Sorry I forgot to say that currently the system is based on Windows 2000, it has 2 GB RAM plus 2 GB virtual memory (overkill?) Data processing works fine untill memory usage reaches around 1.4 GB, after that I receive the error message as shown above and all the parts processed afterwards are...

    STEP importation problem

    Trying to import data from a STEP file (~120 MB) created with CATIA v5r16 by another company I repeatedly fail to import correctly all the data, receiving the following error: "Low memory status, file is partially transferred. Increase memory. Element not created" The machine I'm working on...

    How to delete a meshed area

    I'm not sure this would be the quickest/best way to do it, but you can try the following: - create the mesh based on the area - export the finite element information (either using the CDWRITE command - CDWRITE,DB,file_name,CDB,,, - or going to Preprocessor -> Archive Model -> Write and...

    Boundary conditions on nodes

    From the ANSYS manual entry for FLUID142: The FLOTRAN element must be in counterclockwise order for a 2-D FSI analysis (for Figure 141.1: "FLUID141 Geometry", I, J, K, L order) and it must be in positive volume order for a 3-D FSI analysis (for Figure 142.1: "FLUID142 Geometry", I, J, K, L, M...

    3-D input devices by 3dconnexion: any good?

    Recently I have been looking up at the input devices (like the SpaceNavigator or the SpaceTraveler) produced by 3dconnexion, and I'd like to test them to see if they can really deliver what's being advertised; before buying one though I'd like to ask if anybody here has had any experience with...

    Mirroring Loads and BCs in ANSYS

    By reflecting the meshes you can save a (usually) small time on the total spent on the modeling; the most useful aspect of reflecting (based on my experience of course) is to be found in the global mesh to be more 'regular', with constant number of elements and nodes in every volume/surface etc...

    Mirroring Loads and BCs in ANSYS

    The two meshes can be combined simply by using the Merge command (NUMMRG, applied to nodes); if by reflecting the volumes you reflect the meshes as well, to combine (by merging, gluing etc) the areas you'll have to clear the meshes as you would receive an error message otherwise, and then merge...

    Structural Problem When Importing Parasolid File Format

    Try the following: - when importing, set the "Geometry Type" to Solids Only or All Geometries - after importing the part, Ansys by defaults sets the viewer to show the wireframe of the the model; try setting the Solid Model Facets to Normal Faceting (PlotCtrls -> Style -> Solid Model Facets or...
