    Try:
     
    "C:/Users/Nutzer/Documents/Studium/zz_IAV/z_Test/Skript_einlesen/test.UFF"

    Numerically, both meshes can give the "same" results.
    The 2nd is "nice" to see, but nothing is guaranteed his numerical result is better than 1st one.

    In my version 2019.1 I can choose between 2 modes: Ranged & Discrete


     
    May be the limitation of student release?

    Here's the pattern of your mid-surface:

    Wow, it's a very big CAD model. Even with small part of this CAD, Hypermesh can't extract mid-surface.
    So the only way is try to understand construction logic and build directly mid-surfaces.
    Good luck!

    If you have a lot of memory RAM, this option will force to solve in memory:

    What do you do to create this Spring element?
    I think the way: Mesh -> Create -> 1D Element -> Springs -> ...., right ?

    Which CARD image do you use for Spring property?

    Hi Alex,
    In shell stress results you have several results for different layers:
    Layer = Middle => Membrane stress only Layer = Top/Bottom => Membrane stress + Bending stress HTH,

    @Janeiro: for your model, you can begin with 2D mesh (see my picture) and then build 3D mesh by "drag". It's so simple!

    Have a look at 2D mesh within "^Surf_1"  & "^Surf_2" and you will understand:

     
    HM model: Pedal.hm

    Contact your Altair local vendor.

    If you know surface ID, you can select points by:
     
    hm_createmark points 1 "by surface" $surf_id

    In fact it depends to you work and to your working method. With more than 20 years of FEA I never need this feature

    Some lines to give you some ideas:
    foreach eid $elemList { set config [ hm_getentityvalue elements $eid "config" 0 ] #----- RBE2 ----------- if { $config == 55 } { set independentNode [hm_getentityvalue elements $eid independentnode.id 0] set elemNodes [hm_nodelist $eid] eval *createmark nodes 1 $elemNodes eval *createmark nodes 2 $independentNode *markdifference nodes 1 nodes 2 set elemNodes [hm_getmark nodes 1] puts "RBE2: $eid = $independentNode \[ $elemNodes \]" set new_eID [proc_to_make_RBE3 $independentNode $elemNodes] } }

    I tested alot with SimSolid. It's nice tool for designer, but NOT for FEA Engineer
     
  19. Alex Nguyen liked a post in a topic by Q.Nguyen-Dai in HEXA MESH   
    When you see the message "non mappable ..." it means that I can not do mapping hexa mesh. Sometimes I can do split more to get, but sometimes it's not possible. It's not geometrical error. Just the software can not do mapping mesh to get hexa mesh and it's mathematical.
  20. luis.rodriguez liked a post in a topic by Q.Nguyen-Dai in Solids vertices change at the time of splitting with surfaces or planes   
    Yes, I have got the same issue for some time. Here're my tries:
    Check the geometrical tolerance (pres O) Try to isolate the volume which causes the issue by splitting solids Try to work with surfaces instead of solid

    Which "Card image" do you use for your material?  If you use "MATERIAL", you can try:
     
    hm_getvalue mat id=1 dataname=MP_EX_VAL2  
  24. llyle liked a post in a topic by Q.Nguyen-Dai in how to get thickness of elements as a list?   
    If element thickness was assigned via component, not directly by element, this command returns nothing. In this case you have to call "hm_getthickness component"

    Try to put your commands in a proc & call this proc via -command ?
    Remember : the valid command is "*create....." not "create...."
