1. ## Modeling Gravitational Fields with Planets in MotionView

Hello Is there tutorials anywhere(or your help) that can help me with modeling gravitational bodies, say like planets, within a gravitational field within MotionView? My ultimate goal is to model Earth revolving around the sun and launching a spacecraft from Earth to Mars all captured within Motion View -Thank You

3. ## Point to apply gravity or acceleration

Hi , I would like to understand why INSPIRE asks me a point to apply gravity ou acceleration in translation ? To my mind , the gravity or any acceleration in translation is applied ti the whole body , not especially in one point. I'm wrong ? what is the consequence to apply gravity on a random point ? BR VV
4. ## Roll over analysis

Hi, I'm new to radioss. I'm carrying out roll over analysis on box as shown in attached image. i've assigned initial velocity along axis and got the box roatating, the problem i'm facing here is the box is being thrown upward and its not falling on the base.do i need to assign gravity? if so how?
5. ## Apply gravity in hypermesh for abaqus solve

Support, How is gravity applied to the mesh in HM? Are all nodes selected and then a magnitude specified? Regards B
6. ## Multiple gravities

Hey there, i got a problem with my optimization. What i want to do is addig 4 gravity loads on my component in various directions. well i know the option to create a load collector and card edit it to "grav". But then i would have to create 4 load collectors and the problem is how to assign 4 loads into my loadcase? So what i tried to do then is just applying 4 forces. Because i know the mass of my component i can easily calculate the force. so i tried to apply the 4 forces on the whole component with the various directions. But now i get a error # 1000 saying incorrect data in field 3 - "FORCE 2 0 1.0 0 ......" Perhaps i may have a big fallacy but i just dont know how to solve that problem With best regards EDIT: I think i found the problem but i dont know how to delete this topic :/
7. ## 重力の設定

重力の定義はGRAVカードを用います。 GRAVカードはHyperMeshの荷重コレクターであり、モデルブラウザ上でマウス右ボタンによるポップアップメニューから、Create >> LoadCollectorを選択します。 エンティティエディタでは、Card Image = GRAVにし、G欄に加速度を、N1,N2,N3で加速度がかかる方向のベクトルを指定します。 下の例では、Y負方向に重力がかかることになります。（mm, N単位系では、9800mm/sec^2の加速度） 添付のgrav.femファイルは下図のようにバネを吊り下げたサンプルです。 バネ長10mm、バネ定数100N/mm、バネ上端完全拘束、バネ下端に10kgの質量を付加した状態で、自重（Y負方向の加速度9806.15mm/sec2）を考慮 grav.fem

9. ## Apply Gravity on COG

How to apply gravity load on COG? should i create Rigids for whole body and apply gravity load on that?? but my model already as rigids for few parts, wont that produce errors?
10. ## How to impose an initial velocity on a rigid body?

Hello everyone, I define a rigid body by selecting three components as slave nodes and the primary node is selected as calculated node. An initial velocity and gravity load were wanted to be imposed. I tried, but it didn't work. So I want to know how to impose initial velocity and gravity load on rigid body correctly? And how to select the master node of the rigid body? Best Wishes! Roy Duan
11. ## Gravity in forming simulation

Hi! I am using the RadiossBlock (Block140) in Hypermesh for a forming simulation and I want it to consider the force gavitational, can you please help me? I already read the tutorials in the page, but I think they are not based in the same Block that I am using, but in he Abaqus (Standad3D) block. Thank you very much in avance.
