    Hi,

     

    Finally I got the answer for my question, Here is it have a look.

     

    There are 2 options to do so

    1)      Menu bar>mesh>create>midsurface>

    2)      Utility menu>Geometry mesh>midsurface thickness

     

    Note: need to create a dummy property named as “t0” and the property as Pshell (no need to give any value for thickness, leave it as is.

     

    1)Menu bar>mesh>create>midsurface>

    This option will automatically extract the midsurface and assigns the thickness according to it. But it will do auto surface editing after extracting the mid, It may not connect the surfaces as required.

     

    2)Utility menu>Geometry mesh>midsurface thickness

    This option will consider the existing elements for assigning the thickness. Here u r allowed to do the surface editing. But the surface which u r meshing should be extracted mid surface of the required Geometry.

    Hello ravi,

     

    For example consider load is varying from 1N to 10N on a cantilever plate .

     

    In that case you have to create two forces of 1N and 10N at the end of the load region.

     

    Go to> Analysis> Force>

     

    Under Global coordinate system change the load type from "Constant vector" to "Linear interpolation" as shown in the figure 1.bmp.

    assuming that you might know why we do mesh at mid-surface rather mesh it on the outer or inner surface, i directly come to ur question about thickness. 

     

    1. Our meshing should always represent the geometry because the stiffness matrix varies with respective to the geometry, shape and size(in x,y,z ) on which the stress and defections values are based. 

     

    2. irrespective of element type Software requires all 3 dimensions to run an analysis so, For 1D elements, it contains the information of only 1 dimension(say x) but later while defining the cross-sectional parameters we provide the information of other 2 dimensions (y and z). similarly For 2D elements, it contains info of 2 dimensions say x and y, now while assigning thickness we r providing z dimension info. so if u skip defining value even in 1 dimension syntax will fail to execute the analysis request. 

     

    there are some rules to be followed before judging the right element type... but it is irrelevant to the question you u posted so, i'm not discussing it here..

     

    hope it was clear ! .

    Hi kanney,

     

    Mass= Volume*Density

    Here the volume will be in mm3 & density you have given is in Tonne/mm3

     

    So the mass will be in Tonnes (=mm3*tonne/mm3)

    Hi vraeleragon,

     

    In Auto mesh keep the mesh type as trias, clik on the arrow next to "First order" will convert it to "second order",..

     

    now mesh your surface. This will create a second order mesh (i.e. Tria6).

    Can u tell me in which step you have struck. 

     

     I am assuming that you are in step_2 "Setting up a topography optimization in HyperMesh"

     

    In that u have to specify a node ID where u got the maximum displacement.

    (See in page no.5 (point.6) displacement contour gives you the node ID (7373) where the maximum stress was occurred)

    Hi maysam, 

     

    For defining the cross section for 1D Elements, Go to 1D>Hyperbeam>Standard Solids> Standard section library (Will allow u to select the type of solver)> Standard section type (Example Select "Solid Circle")> Create

     

    Will open "HYPERBEAM VIEW" There u can define the parameters.

     

    Note: Before that u have to create a 1D beam property.

    ok,

     

    Just check out Geometry>Autocleanup>topology cleanup parameters> edit parameters

     

    To be frank till now I didn't used this option, I generally prefer manual surface editing (may be I work on small components).

    Hi Keerthan

    if these 2 parts can rotate relatively, connect them by cylindrical joint (dynamic analysis)

    in static analisys, you can connect them by RBE2 or common nodes (share nodes between 2 comps)

    ect,... depends on what you want to analysis
