I have my fortran code solving finite elemnt problems for CFD applications. I'm using ifort since 2010. I was frustrated today to find that test cases I used to solve with no problem are actually not working any more. I spent more than 10 hours today trying to find out why. ifort 2011 works fine, it is 2013 which I have just installed on one of my machines. I had to specifically include -fp-model source in the compiler options in order to get ifort 2013 to work. I also included -fimf-arch-consistency=true . I'm wondering what is the detault -fp-model in 2013 and why you have changed it from that of 2011. I'm also curuis about how much would speciifing both option affact the performance
Thanks!
