Hello,

I am trying to run a somewhat large analysis (about 120k CPE4R elements) using double precision in Abaqus/Explicit 2023. I am using a VUMAT, which I have validated using single and double precision using single-element tests, and using single precision for the large analysis. However, when I try to run the analysis using 'double=both', I am getting the following error (the subroutine compilation and input file check complete successfully):

Run package_dp.exe

 ***ERROR: Abaqus/Explicit has encountered an internal error during the

 ***ERROR: analysis. Please report the issue to local office.

It also says to check the status file, but the generated .sta file is empty. 

I am at a university, and our IT department just referred me to this support forum for help with this issue. If anyone has some suggestions for debugging this issue, I would greatly appreciate it. Thank you!
