i am working with hetval subroutine with state variable (statev) in cae 2020. my subroutine is as follows.

CHARACTER*80 CMNAME
DIMENSION TEMP(2),SVAR(1),PREDEF(1),TIME(2),FLUX(2),DPRED(1)
C
FLUX(1)=0.45
STATEV = 2.14TEMP(2)+5
RETURN
END

what ever value i gave for STATEV, odb output always gives 0 for SDV1. in another word if i write STATEV=5000*TIME(2), SDV1 gives zero for all increments. what would be the reason for this behavior of SDV1
