Two UMATS in one Subroutine
Tue, 2012-02-28 04:07 - ABAqirl
Dear All,
I have the problem. i created very simple example with two elements. To one element i prescribed the behaviour Mat1, to another element Mat2. I tried to use two different UMATS for this two elements.
I created Subroutine Myname.f, in which i use CMNAME if (CNMAME.EQ.'MAT1) THEN
CALl UMAT_1()
ELSE IF (CMNAME.EQ.'MAT2) THEN
CALL UMAT_2()
END IF
Then i put two UMATS in the same SUBROUTINES ,
But as a result the program gives MISTAKE , it says that The UMAT doesn't exist
What is the mistake?
IN MYNAME.f and in ALL UMATS i put the lists of arguments as in USUAL UMAT.
Could someone help me?
Best regards
ABAgirl

First of all, does your
First of all, does your implementation work for one UMAT case? If it does, are you defining two separate user materials in the input file with the specific name, "MAT1" and "MAT2"?

Thank you for help!
Thank you all for the kind reply,
I did everything correct, the problem was that i work with file in Windows and when i transfer UMAT into Unix mashine, there were strange symbols and of course abaqus didn't understand what it is saying thet umat doesn't exist,

Why you don't use a Logical
Why you don't use a Logical test with response : false and true ? it takes less memory.
good luck
Hello Mohamedlamine, What
Hello Mohamedlamine,
What do you mean with Logical test?
Re: UMAT
Dear ABAqirl,
Instead of Testing a Character String which is not easy to match in Fortran you may use a Logical Variable
for example :
LOGICAL RESP
RESP=.FALSE.
.....
IF (RESP) --------------> your first case
..
ELSE
--------------> the second one
ENDIF
