    On the inf-sup condition for the P3mod/P2disc element

  • Original language description

    We consider a recently introduced triangular nonconforming finite element of third order accuracy in the energy norm called P3mod element. We show that this finite element is appropriate for approximating the velocity in incompressible flow problems since it satisfies an inf-sup condition for discontinuous piecewise quadratic pressures.

    O inf-sup podmínce pro prvek P3mod/P2disc

  • Czech description

    Uvažujeme nedávno zavedený trojúhelníkový nekonformní konečný prvek třetího řádu přesnosti v energetické normě zvaný prvek P3mod. Ukazujeme, že tento konečný prvek je vhodný pro aproximaci rychlosti v úlohách nestlačitelného proudění, neboť splňuje inf-sup podmínku pro nespojité po částech kvadratické tlaky.
