getting material property in ABAQUS

Hi, everyone,
Now I have a problem with getting the material property at each increment from ABAQUS. I have written a USDFLD subroutine to change the material properties at each increment. but I can't monitor the variation. do you have any idea how it is possible?

Thanks

Hello, I am facing a similar problem with you, I use USDFLD defined a functional gradient material. However I don't know how to call the mechanical properties defined in USDFLD to UMAT, have you already solved the problem? Thank you!

First you have to make sure that the properties are defined in USDFLD properly. You may check that my printing.

Then you may use a fortran module which has the variable correspoding to the properties. Suppose you have defined 2 properties then module will have 2 variable. The values of these variables can now be updated in the USDFLD variable and can then be used in UMAT. 

But My guess is there should be no need of such thing.

See if this works. You may also send me the file. I can look into it for you.

Good luck to you both
