floating pont error with DKT + BETON_DOUBLE_DP

Hello everyone / Bonjour a tous

I'm trying to simulate a concrete slab with dkt+grille excentree

I defined the concrete as being BETON_DOUBLE_DP but all I'm getting is

   !-------------------------------------------------------!
   ! <F> <DVP_2>                                           !
   !                                                       !
   ! Erreur numérique (floating point exception).          !
   !                                                       !
   !                                                       !
   ! Cette erreur est fatale. Le code s'arrête.            !
   ! Il y a probablement une erreur dans la programmation. !
   ! Veuillez contacter votre assistance technique.        !
   !-------------------------------------------------------!

What can/should I do?
Merci d'avance

Re: floating pont error with DKT + BETON_DOUBLE_DP

Dear All,

I have got the same error as in this old post. Is BETON_DOUBLE_DP incompatible with DKT modelling? In u3.12.01 I read:

Seules   les   modélisations  'DKT' et 'DKTG'  disposent   de   possibilités   non-linéaires.   Les   lois   decomportements     spécifiques     à     cette     modélisation,     utilisables     sous    COMPORTEMENT    dans STAT_NON_LINE  et  DYNA_NON_LINE  sont   les   relations   de   comportement   en   contraintes   planes disponibles avec les modélisations 'AXIS' et 'C_PLAN'(cf. [U4.51.11]).

and in u4.51.11, par. 4.4.7.9:

’BETON_DOUBLE_DP’
....
Modélisations supportées : 3D, D_PLAN et AXIS

So I am a bit confused. Could you please help me on this regard?

Thank you and best regards,

Corrado

Re: floating pont error with DKT + BETON_DOUBLE_DP

Hello,

for 1D and 2D element you can use nonlinear behaviours due to methode D'BORST. Behaviour BETON_DOUBLE_DP has not implemented this method. You can use for example ENDO_ISOT_BETON, ENDO_ORTO_BETON, MAZARS..... All usable method with the borst are specified by word BORST at supported local modelings in u4.51.11.
