Hi,

 

I want to morphing hexa/penta seat cushion with Radioss?

I often use P14_SOLID for Hexa and Tetra elements but unable to run with Penta elements?

 

Could you advise for this?

 

Thank you.

    Hi,

    The pentahedron element is currently only supported as a thick shell Isolid =15 element and used with /PROP/TYPE20 (TSHELL).

    Thank you George very much for your fast response.

    I have never used thick shell solid. Could you explain the difference b/w normal solid shape element and thick shell solid for application purpose?

    Hi,

    In the same file with property P14_SOLID please update the element type (2D>>elem types) of penta elements (keep the element type to PENTA6DG) and see whether it works.

    Hi George,

     

    Appreciate your prompt support again.

    I update Penta elements to PENTA6DG and Radioss ran pretty well.

     

    Thanks again!
