hello. sorry for interrupting. can you help me? i am not quite familiar yet with hyperworks software. i am using hyperwork 11. i got stuck when doing the analysis for my project which involving the heat transfer @ thermal analysis. i want to analyse the heat transfer inside the motorcycle helmet which is convection heat transfer and conduction heat transfer from surrounding. i want to cr​eate temp inside helmet and outside helmet. i have try to refer to the tutorials but it not quite help bcause the tutorial is not a quite complex object such my project. i have tried many times but still not able to produce the result i want. can you show me step by step how to make thermal analysis or tips to make thermal analysis for this? this is my model.
 


 



is this model need meshing again? i make meshing using 2d but still got 4 failure for the model. however i got stuck at creating inside temperature and outside temperature. how can i solve this? anyone can help?

    Hi Syamil.

     

    If I have understood it correct, you want to model an intial condition inside the helmet and ambient temperature as the outside temperature.

     

    Go to Analysis>> Temperature and create temperature for inside. Now, create a DLOAD card and refer the TLOAD1 in this DLOAD.

     

     

    For the rest you can give through TEMPD. TEMPD is available as a load collector.

     

    When creating loadstep for heat transfer, Refer TEMPD card for IC and , you can refer to DLOAD created in above step in the subcase directly.

    Hi Prakash,

     

    Thank you for your help. I will try to do the analysis first based on what you told.

    Syamil,

     

    The analysis type will be transient. So you need temperature data varying with time. Please keep a note of this.
