Hello George,

I checked with the development team and I got the following reply:

" should be working for both ELFORM 10 and 13. ELFORM 10 and 13 is suited for compressible and nearly incompressible material models (both available in MAT_295), respectively. It should even work with ELFORM 15 and 16 even though those elements are not recommended even by their developer. Which LS-DYNA release is the customer using?"

Could you tell us  which  version of LS-DYNA you are  using?
