troubleshooting user subroutine with abaqus 6.10
Im trying to implement subroutine umatht(user defined code is written in 2006- not sure which version of abaqus is used?! ) and run a job.However, i,m getting this error through abaqus cae and cmd .Im using abaqus 6.10 -VS2008-IVF 11 AND successfully run some examples from abaqus verification.i also can send my fortran file ( .for) and input abaqus file for more clarification if you require.
is it possible that mismatching abaqus version cause this kinda error?i mean running a subroutine(written code in 06) is it sensetive to abaqus versions(6.10)?
E.obj= error LNK2019: unresolved external symbol state referenced in function UMATHT
E.DLL= fatal error LNK1120: 1 unresolved externals
ERROr on cae :
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
any help really apreciated.
