NGI-ADPSoft for strain softening behavior of the clay

Question

Hi support team 
 I am using the plaxs2d connection edition V 21.01 and I would like to find a constitutive model which can simulate the strain softening behavior of the clay. I read several publications that NGI-ADPSoft model can simulate the strain softening behaivour. 
 Unfortunately, I can not find the NGI-ADPSoft model in Plaxis2d and also any the description of this model. 
 Could you please let me know the NGI-ADPSoft model was implemented in which version of Plaxis2d? 
 Except for NGI-ADPSoft, are there other constitutive models for strain softening of the clay? 
 Thank you for your help, 
 Best,

Dear Jian, 
 PLAXIS has not officially released any version of the NGI-ADP-Soft model. 
 Possibly NGI has released this or may have published research, therefore you can contact them for the DLL for PLAXIS.

Dear Jian, 
 The NGI-ADPSoft model has not been implemented for PLAXIS by us at least, though it could be that NGI themselves did of course. I presume you would like to have strain softening because it's an overconsolidated clay, in which case in PLAXIS we have the OC-Clay model. 
 With kind regards,

Dear Jian, 
 It is indeed SHANSEP NGI-ADP, that is why I removed my remark again. 
 However, you should also have "adp_soft64.dll" and this is NGI-ADP-Soft.
