  1. シェル要素に対し、オフセットした板厚を設定する方法です。 ※User Profile = OptiStructの場合 プロパティのエンティティエディタか、Card Editから "ZOFFS" オプションで設定します。     下記2通りの設定方法があります。   ◎REAL    オフセット量を数値で入力します。   ◎SURFACE    TOP または BOTTOMを選択します。
  2. 2Dページ⇒elem offsetパネル⇒thicken shells機能で、下記の設定でシェルを選択してthickenを実行すると、プロパティや節点板厚情報などを基にシェル要素に割り当てられたから板厚分のオフセットさせたソリッド要素を作成することができます。 ↑実行前イメージ↑ ↑実行後イメージ↑
  3. 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.
  4. 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
  5. Designing a consumer product would require you to do curve projection at least one time unless you are in search of an overall shape. When you do a cutout of a panel/surface in order to insert a piece it is wise to fillet the edges of both pieces for rendering purposes so it ends up looking more convincing but sometimes you really need a bigger gap between two panels/surfaces. This is where some sort of gap tool creation would come in handy just to interactively expand or resize the existing gap when you do curve projection. So far one of the workarounds has been to do offset of the cutout which gives you a leeway to do proper bigger filleting of the edges to close the gap (that way it looks more pronounced in the render). I am not aware of any other workarounds cause I'm lazy to do some creative thinking.
  6. Hey guys, In Hypermesh, under the Ansys User Profile; I cannot seem to figure out how to show shell thickness offsets. Example: 1. I apply a thickness of .5" to a Shell181 group of elements 2. I change the Section Property SECOFFSET optio to TOP / BOTTOM / USER instead of MID 3. Hypermesh still shows the thickness at the middle of the element. To parallel this, I know that the Nastran user profile will correctly display Nastran imposed ZOFFs applied to PSHELL cards. This is the desired affect I am looking for graphically in Hypermesh for the Ansys User Profile. Does anyone know how to view the thickness offsets applied with SECOFFSET in Ansys? Thank you, -aero
  7. 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)
  8. 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.
