The FORTRAN compiler was merged with Abaqus environment successfully. But when I am trying run my UMAT Subroutine code for progressive damage analysis of composite pipe it is not working well. It say problem during compilation. Anyone who help me. I would appreciate.
See the .log file. It will have the error messages printed in it. You can also use print statements in your subroutine code and look up the printed values in the .log file - for debugging you code. This way you can track the values that being computed in your subroutine.
Thank you. Ashok.
As you see in .log file it say problem during compilation or fatal error would appear. How could I use print statement to bring the .log file for debugging my UMAT code.
As I understand the error is related to your UMAT file name.
Give a simple name like mymat.for. Don't forget to change this name in Abaqus - job module. I think you gave the name as "UMAT progress.for". Due to the space in between "UMAT" and "progress.for" it is not able to recognize.
yes it is. I got such .log file is appeared. so how can I debug this.
Hello Tesfaye Tamiru ,
Judging from your .log file that you provided I would say that you are trying to write in a "free-form" format and not the "fixed-form" format. If you do not specify the free-form format then you have to limit the characters used per line is only 72 characters.
So you should either put this statement on the very first line of your UMAT: !DEC$ FREEFORM , so that you may write in a free form format (note that this might require making changing in abaqus.env file), or you should limit your command lines to the allowable character limit.

Thank you dear. Anargyros.
I found such .error message in .log file
would you check my UMAT code and show me how could I debug it.
Tesfaye Tamiru as you may imagine checking a UMAT code would require substantial effort and time.
Yet, I would just try to suggest a couple of things:
1. replace the numbers 1,2,3,4 etc. at the beginning of each line with the symbol "&" that would connect the previous with the next line.
2. make sure that you do not have commands exhibiting the 72 character limit (comments are not an issue)
These two would definitely solve the errors reported in the provided .log file.

Anargyros
Tesfaye Tamiru were you able to solve the reported issue? If so, please share it here so that your question may be considered as answered and the issue resolved.

Anargyros
I got the problem in .log file was solved when I write the code in a fixed format as you recommend me earlier.
Thank you Anargyros.
