    Pore fluid bulk moduli equation

    Hi I was checking the theory manual of the constitutive behavior in a porous medium. The manual provides a general effective strain equation that would include the grain bulk moduli, but it doesn't include the pore fluid bulk moduli (nor does it mention anything about young's modulus) in the...

    How to identify a material in subroutines

    How can i identify a certain material in the subroutine? Like i wanna do something like this if i have material x and y If (material .eq. x) then follow a certain logic if (material .eq. y) then follow another logic. So how can i do that?

    Problem of transfering values from URDFIL to UTEMP

    Hi I am making this model where i am calling some variables (void ratio, pore pressure, etc) and creating others (Bf) using UVARM subroutine. variables are read using URDFIL, then by using common block to transfere the values to UTEMP where i am relating the TEMP to (Bf). The problem is ...

    ifort.exe not found in PATH ?!!

    I keep on getting this message "ifort.exe not found in PATH" when i am trying to submit a job with a linked subroutine. Anybody knows how to fix that?

    problem during linking subroutines

    It works with other models but not this one. Thats why i don't think it is a problem in linking between abaqus and fortran

    problem during linking subroutines

    I am trying to submit a job, and i always get this message problem during linking Abaqus-standard user subroutines. Any clue how can i overcome that?

    Error while trying to restart the analysis

    When i try to restart my analysis, i get this error message and i don;t understand why. ***ERROR: Features such as new nodes/elements, IMPORT, SYMMETRIC MODEL GENERATION, MAP SOLUTION are detected in a continuation analysis where the original model is defined in terms of...

    Change hydraulic conductivity with failure

    I want to ask how can i change the hydraulic conductivity in a soil model in failed elements during analysis?

    fluid bulk modulus as a function

    Can fluid bulk modulus (or fluid compressibility) in soil model, be introduced as a function? (and i don't mean temprature as a variable)

    How to pick up inner elements from orphan mesh?

    what about parition?

    time /day

    Thanks, but the numbers will be very weird and huge if i do so (for g gravity and water specific gravity). i tried to do simple analysis that i know it converges if i use seconds, but it didn't converge at all when i changed all units to day.

    time /day

    I want to use time=day instead of second in my analysis (to identify element permeability). Does this mean i should convert all time units to day? (including gravity m/day2 instead of 9.81 m/s2)?

    Hydrostatic BC

    How can i identify hydrostatic BC ?

    Soil drained BC

    in all soil tutorials, to achieve a drained analysis, loads are applied at one step (using very short time and without releasing the pore pressure) , then during the next step pore pressure is identified to be zero and the consolidation behgaviour is monitored with time. My question is, would it...

    Failure surface

    I am modelling an excavation, and i am wondering which parameter should give me the failure surface (plastic zone). the closest surface to what i was looking for was the AC yield, but still not sure if that is correct. Any ideas?

    Consolidation time

    I figured out whats wrong with the analysis..Thanks

    Consolidation time

    Hi There is something i am not sure i do understand it right. For consolidation (soil analysis-fluid/stress model), when i set a time for the consolidation step (either fixed or automatic) , would abaqus give the results at that time, or would it assume that it is the time for the 100%...
