Abaqus Example Manual

Hello,

I tried to run one of the example files in the Abaqus example manual. The link to the example is http://www.egr.msu.edu/software/abaqus/Documentation/docs/v6.7/books/exa/default.htm?startat=ch09s01aex128.html 

The error that I get in text document is;

Abaqus JOB exa_hydfractureAbaqus 6.14-2Abaqus License Manager checked out the following licenses:Abaqus/Standard checked out 5 tokens from Flexnet server license2.arsc.edu..Begin Compiling Abaqus/Standard User Subroutines5/30/2015 5:57:15 PM'ifort' is not recognized as an internal or external command,operable program or batch file.Abaqus Error: Problem during compilation - exa_hydfracture.fAbaqus/Analysis exited with errors

Method used;

So, it has two files viz; .inp and .f

I used abaqus job=job-name user={source-file | object-file}  to run the files in abaqus command box

Note: I made the necessary changes asked for in .inp file as mentioned in the example. Please suggest!

I have tried several things but the example problem itself doesn't run. Please help!

Thanks,

Aditya
