Hi,

I am using ABAQUS 2021 and need to implement user subroutines with Fortran. However, I run into some issues for compatibility between ABAQUS and Intel Fortran Compiler I use. I use ifort 2021.13.1, and I need to read data from external files in UEXTERNALDB during the ABAQUS simulation. But sometimes the simulation can be disrupted by the following error:

forrtl: severe (24): end-of-file during read,...

The content of the file is just a string, and this error just occurs sometimes, not each time I run the simulation. I am wondering whether it is due to incompatibility between ABAQUS and the ifort version? Also, it seems that older versions of Intel Fortran Compiler is not so easy to get online. Is there any alternative solution if I need to downgrade the Fortran compiler? Thanks a lot!
