iMechanica - constant material properties in user-defined subroutines in ABAQUS - Comments

If I use a User Material

If I use a User Material in ABAQUS, it gives me an error that there is no sub-routine supplied.

So my question would be, if I have User Material selected and I define my constants how can I "assign" the subroutine, (I have already selected the subroutine fine in the options under edit job)

Not hard

PJ-

When you choose a User Material in CAE, it allows you to add whatever material constants you'd like.

I am having the same issue,

I am having the same issue, where can I define the constants for my user subroutine in CAE ?

constant material properties in user-defined subroutines in ABAQUS

Hello, I just started using abaqus couples of days ago, so this could be a very basic question, but I have no way to deal with it even after I spent hours with abaqus manual.

I'm using a user-defined subroutines for hyperelastic material in abaqus (UHYPER). I got a fortran file that defines the strain energy density with some material properties that need to be passed to the subroutine; they are defined as 'a = PROPS(1)', 'b = PROPS(2)', etc., and 'a' and 'b' are used to define U(1), UI(1), etc. in the fortran file. However, I'm wondering where and how can I define the numerical values (constants) of PROPS(1) and PROPS(2). I guess they should be specified outside the fortran file; maybe during creating MATERIALS in Abaqus CAE. In 'Edit Material' window of Abaqus CAE, I can set the 'Number of Property values', which I guess 'Property values' means PROPS(1) or PROPS(2), but not the actual numerical values of them. Can anyone tell me how can I define the values in Abaqus CAE?

Finally, in the fortran file (user-defined subroutine), 'TEMP' is used in defining U(1), UI(1), etc. Again, how and where can I set the numerical values of 'TEMP' in Abaqus CAE?

Thank you!
