Obscure FEMAP Errors 2

[generaluday]

I've been trying to solve the static analysis example of the assembly with the "contact" connection property provided in the femap help system. I have solved this before with success, but below is the list of obscure errors femap throws at me when I try to solve it this time.

I use femap regularly, and most of the time it works fine, but every now and again I get these errors even if the setup seems correct no matter how many times I check it and redo it.

Can someone explain to me what might be going on here? I'd appreciate some help.

Hello!,
You show us the content of LOG file, but also the *.F06 file is welcome. Make sure you have write permissions in the directory "c:/users/udayraj/desktop/femap asy/".
Try to create a new subdirectoy at the root level, say D:\WORK and copy your FEMAP file there and run the model.
Also, check the NX NASTRAN RC file nast7.rcf, make sure the variable SDIR is correctly setup.

Check if any virus is installed in your system. Good luck!.
Best regards,
Blas.
