Hi, I wanted to ask if the variables/parameters defined in the online Hypoplastic model manual for PLAXIS (https://web.natur.cuni.cz/uhigug/masin/plaxumat/node6.html) are the same for the ABAQUS UMAT?

SImulation with hypoplastic model for granular materials in ABAQUS
Hello, I want to use the hypoplastic model for granular materials downloaded from https://soilmodels.com/download/plaxis-umat-hypoplas-zip. The UMAT file umat.for is the model for sand. I followed the instruction https://web.natur.cuni.cz/uhigug/masin/plaxumat/node5.html. I have […] -

Dear Hashmi,
Basically yes, the most of the input you can see that it is identical if you check the subroutine: subroutine check_parms_h in the umat_hcea.for
Best regards,
Hans
Hi Hashmi, yes, they are.
Just for state variables you can use sdvini in Abaqus for their initialisation. But Plaxis way, that is initialisation through parameters, will be functional in Abaqus as well.
thank you for these info!
