Hi,

I want to change initial velocity of this model;.

 In manual, check load case and initial velocity. But i cant find any velocity of this model.

 

Please show me how to change initial velocity of this model. File attached

 

Thanks.

    Hi Baesh,

    In the model file attached there are no loads or boundary conditions. 

    To provide an initial velocity in the model, Please go to Utility Menu in the model browser and select BC's Manager. Provide a name for the load collector and select the type as Intial Velocity from the menu. Then select the nodes or parts where velocity is to be applied and then provide the velocity in the required direction (Vx or Vy or Vz).

    Please find the attached image.

     

    Meanwhile, please go through this video series where pre-processing for crash analysis is shown as an interactive tutorial. All aspects of FE modelling are covered here with a full car model. Creating initial velocity and boundary conditions are shown here. Please access the videos at : http://www.altairuniversity.com/getting-started/learn-radioss-training-webinars/

     

    We have an online learning and certification program for Altair products. All aspects of explicit analysis using RADIOSS is also covered there. Please access http://certification.altairuniversity.com/ for more details.
