I have Abaqus 2020 linked to intel oneAPI and it runs run ok until I had this issue. "error LNK2019: unresolved external symbol ROTSIG referenced in function umat.R" ROTSIG is a call inside the UMAT. Is there any quick way to fix the problem. I use VS 2019 for compiling. The error statement is below
Begin Linking Abaqus/Standard User Subroutines
Creating library standardU.lib and object standardU.exp
swell.obj : error LNK2019: unresolved external symbol ROTSIG referenced in function umat.R
standardU.dll : fatal error LNK1120: 1 unresolved externals
Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.
This error may be due to a mismatch in the Abaqus user subroutine arguments.
These arguments sometimes change from release to release, so user subroutines
used with a previous release of Abaqus may need to be adjusted.
Abaqus/Analysis exited with errors
Thanks in advance!
ROTSIG is an Abaqus-supplied subroutine. It is not part of standard Fortran or supplied by Intel. There are a small number of Abaqus users who are members in this forum, but your best solution would be to ask Abaqus and Abaqus user forums.
