How to apply initial velocity in Optistruct

Recommended Posts

Hi Vikas,

Kindly let me know if you need more details on the request. I've seen that there is a option called "InvelB" but, I am not sure what it mean by Body identification number and how to define it?

Hi Suresh,

 

If you want to carry out a drop test, I would suggest to use RADIOSS which is based on Explicit techniques. 

 

In Radioss you can apply initial veloctiy through /INVEL card which is supported through HM

 

Thanks,

Vikas

Hi Vikas,

 

Thanks for your reply.

 

Does Radioss support fatigue calculations? Ideally I would prefer to go with Optistruct as I do not have prior experience in Radioss block format. Could you please suggest any equivalent method to do drop test in Optistruct followed by fatigue?
