Hi

I am new user on using radioss solver ; And deck is prepared in HYPERCRASH

I am performing Impact (Forming) simulation ..! I Have used these parameters on for adaptive meshing global. .

But in result file , Adaptive meshing is not applying on blank.( So simulation is not converging).! Could you pls help me in setting the right parameters

 

1. Output Error file : Pls view the attached gif file

2. Parameter used for adaptive meshing global :
ScreenShot268.jpg.b9e38549c404675e05d07c626ce4451f.jpg

 

3. Type 7 contact interference is used in model , & also type 10 ( Between blank & radius in Die)

 

Pls help me in clarifying the query or let me know other possible methods in solving the error

 

Let me know if you need more information

 

 

Thanks & Regards

Sai Krishna

    Hello sai krishna,

     

    I would like to help you regarding Forming simulation. You can make use of HyperForm to prepare the deck rather using Hypercrash. In User profile select Manufacturing Solutions and Incremental Radioss for using HyperForm

     

    For forming simulation we use Rigid mesh for tools and Blank Mesh for the blank. Adaptivity is always defined for blank.

     

    Please follow the tutorial files to setup a simple forming simulation. Attached file for your references. 

     

    regards

    Hi santu

    Thanks for the reply ; On forming simulation as you mentioned i use the same fundamentals of rigid body mesh for Die & adaptive mesh for blank.

    For current scenario , adaptive mesh global card is not being considered for the parameters i have selected

    The simulation i am trying to solve is Thermoforming ..! 
    The warnings & errors were for the above thermoforming simulation.!

    Thanks& Regards

    Hi Sai,

     

    For Thermoforming/Hot Stamping we have a separate user template. You need to follow the help files for Hot stamping. 

     

    Below image shows the option for hot stamping.
