    USING DLOAD in ABAQUS

    actually I did. I am using the Intel FOrtran 9.0 with Visual c++ 6.0 and ABAQUS 6.4-1. I had to install a different version of VC++as the other one was corrupt and it didn't give this error but it still gave some other error. I asked the ABAQUS helpdesk . They sent me a workaround for Intel 8...
