Property type for tetramesh

Hello,

 

I modeled foam with tetrahedral elements and wondered what property should I use? In fact, I understand it's isolid, but what options should I add? It works, but I have hourglass problems I think. It's foam under impact.

 

Thanks!

    Hi thanks for your response,

     

    I'll try it, but for tetrahedron, can we use 

     

    Isolid=1, Ismstr=1, Iframe=1 and IHKT=1 (I don't find that one) like the mentionned post suggested?

     

    Thanks!

    Hi,

    For tetra elements Isolid will not work. You can use Itetra option instead in the property card. 

    Create output block for all components and plot the hourglass energy graph for all components and thereby find the component responsible for high HG energy.
