    door Closing Analysis

    Hi Nagarjuna Gundamsetty, I would suggest Motionsolve, which is a Multibody Dynamics solver. Please refer to the tutorial MV-2021: Simulating an Automotive Door Closure Event. You may also find useful the presentation from 2nd European HyperWorks Technology Conference: Door slam simulation for durability analysis with Multibody Dynamics.

    shells on interior solid faces

    Hi 3D---> detach all elements (not detach from, simply detach) ---> take faces for detached elements, now give equivalence to all detached elements (shift +F3), now F10 ---> 2D --> Duplicates--> save failed Create new collector in model browser --> organize all the saved elements in the new collector by using 'retrieve elements'

    About Flexible bodies

    Not sure what you mean by methods similar to modal analysis?

    About Flexible bodies

    Because to estimate internal response (like stress) for the applied external loads

    About Flexible bodies

    Hi Lokesh Katari Rigid bodies are ideal representations of solid bodies or parts of fixed shape and size. They are highly useful in simulations where deformation of a part is negligible. A rigid body has 6 DOF, and each rigid body added to a system adds an additional 6 DOF. Flexible bodies, or flex bodies, are used to model elastic deformation of bodies in a system. The flex body connects to its neighboring elements and bodies through interface nodes.

    Can't create 3D mesh

    Hi Iulen The free edges on the model has been fixed and the file is shared with you. You can now do 3D tetra meshing as it encloses a volume.

    Hello Pandurang, I suggest you to type following keyword to your .inp file under *step section; *el print peeq, *node print u, these codes writes desired results to .dat file. Thus, you can parse that file to obtain results by tcl or python scripts

    Student license - License error

    Hello hang1122, From the screenshots, everything seems to be correct. Clearly the license manager is not able to read the file, but according to your images the file is located at the correct location. Could you copy / move the file to the default location (C:\Program Files\Altair\2018-edu\security\ and see if that changes the error? The only thing I can think of after that is that the file contents is somehow corrupted? What happens if you go to the Licensing Student Edition tab of the Feko Launcher and open the Altair License Utility (ALM)?

    Can't create 3D mesh

    HI, Is it tetra elements or Hexas? First, make sure your surfaces are closed or not. If it is closed, you can use Volume tetra to fill the component with tetra elements Or 2D mesh the component and make sure it is closed. When it is ready, you can use tetra mesh

    HI @Karthic You can use any of one. Here is an example file for RFORCE which uses transient load case. But you can extend RFORCE to FRF RFORCE.fem

    For old way doing TRB optimization was to use gauge optimization and link the DesVars via an equation and limit the thickness change with a constraint. but there of course you need to know/define the zones upfront with different properties. Since OS14 there is another more straight forward way directly aimed to produce TRB results. There you use FreeSize optimization with linear/planar pattern grouping. planar is better choise in case of curved structure as a B-pillar is. In addition you can/should apply thickness gradient constraint in DSIZE-card, so that thickness change is limited to the value which is manufactorable with TRB. So this new way is very easy to setup, as you need only 1 property and 1 DSIZE-card. Thanks Kristian

    If this is what you are looking for, CMS is not a modal analysis and this can be used in structural analysis as well. To learn more, please refer to Finite Element Analysis (Superelements)

    Element Duplication (Overlapped)

    Hi Nut, In order to fix the duplicate elements go to check elems menu (F10) >>duplicates >>save failed. Now go to delete (F2) menu select elements >>retrieve >>delete entity. This will delete the duplicate elements from the model.

    You should not choose 2nd elements while meshing because it will mess up your model just switch 1st to 2nd elements by panel "order change" prior to export the deck
