[Getfem-users] new fem from the scrath

[Egor Vtorushin]

Dear Yves

I've used Getfem++ some years ago and since that moment i'm thinking that this library does pretty much cover FEA needs.

Right know i'm solving some dynamic elasticity problem with redundant requirements of strain smoothness. The decision has been made to proceed with mixed elements solution when strains are from H_div space and velocities are from L2. It led me to strains approximations that looks like this(mostly i took it from  BECACHE, JOLY, TSOGKA 1999 year work)

(same pic attached)

It looks like something in the middle between RTQ1 and QK(2,1) i think. 

Could you please  provide me with a hint how to start implementing this. I've searched the mail-list but was not able to find good materials could help me

Thank you,
