  1. solid face offset

    Hi all, Can you suggest me what is the fastest way to offset a solid face in Hypermesh? In the picture attached I want to reduce the shank diameter for example.
  2. Hi, I am relatively new to hypermesh, please help me with the following queries. Thanks for your time. Query 1: I have to model a beam element with square cross-section which comes in contact with 2D shell and represent the connection between them. For example, if the beam was a hollow square tube and a sheet metal comes in contact as illustrated in the picture below. Is there a way to represent the centroid of the tube on the midsurface of the sheet metal just by providing the offset distance, instead of representing the connection between them using rigids. I would also like to identify where the bar’s central axis lay in relation to the connection points. Query 2 : How to view the 1D elements in 3D representation, showing the cross-section and the orientation of the element with respect to the sheetmetal. ( in this case as shown below)
  3. Submitted by murthyakella on Mon, 03/26/2012 - 20:56 Hi, I want to achieve a space vector with magnitude V(0 to Vmax),frequency of rotation omega (=2pif where f= 10 hz to 50 hz),and an initial phase angle phi (=90 degrees w.r.t. stationary stator reference frame): V= V. e^(jwt).e^(j_phi) So I wanted to use space vector genertor block to get the corresponding phase values. However I am little confused about configuring the frequency scaling and offset in SVG block. Here are my quesions: 1. Which parameter should i set to make sure that the initial phase angle of my space vecor is 90 degrees? "Offset" parameter of this block does not accomplish phase shifting(i.e. horizontal shifting) but rather accomplishes shifting peak value(i.e. vertical shifting) . 2. How do I set the frequency scaling so that when I give an input of 1 p.u. as frequency gain, I get output waveforms of 50 hz? Does it depend upon some other paramters such as system simulation step size or frequecy of microprocesser on my computer or frequency of my texas instrumens microcontroller? Note: Currently, I am getting this value by hit and trail basis (for xample: frequency gain of 3 when simulation time step is 0.01 secs). But I have to reconfigure he frequency gain everytime I change simulation step size (in terms of time or frequency). This approach without understanding the basic concept behind frequency scaling is not a convincing approach for an engineering student. So I am posting my query here to understand the concept behind it. 3. What is the significace of this fequency scaling? How and why does it depend on the time step of the system simulaion? Also why does i get a straight line as output when I give frequency input as 1 and frequecy scaling as 1. I could no find any soluion for these problems in forums or documentation. Hence I would be graeful for any help on this problem. Regards, Murthy
  4. Line Offset - Lines Panel

    When creating a LINE OFFSET using the LINES PANEL, how is the direction of the offset determined? If the line is a planar curve, then it would make sense that it would stay on that same plane. If the line is straight, or non-planar, then the direction of offset seems arbitrary. Also, if the original line is on a surface, is there a way to force the offset line to fall on the same surface? Thanks for your help clearing this up.
