Issue passing data from Starter (USERWIS) to Engine (USERWI) in custom interface

StavrosPant

Hi

I am trying to use a custom subroutine to calculate a custom contact interface between two objects

I have an issue connecting the starter and the engine runs.

In the starter run, im assigning the memory allocation (USERWIS_INI) and values (USERWIS) for IUVAR and UVAR while maintining all other values as Radioss assigned them (IIN IOUT NUMNOD etc.). Up until USERWIS everything seems good

1. IIN : 30
2. IOUT : 31
3. NUMNOD : 676
4. NUVAR : 6
5. NUVARI : 2

UVAR( 1 ) = 5.000000000000000E-002
UVAR( 2 ) = 3400000.00000000 UVAR( 3 ) = 0.000000000000000E+000
UVAR( 4 ) = 0.000000000000000E+000
UVAR( 5 ) = 150000.000000000 UVAR( 6 ) = 1.000000000000000E-003

IUVAR( 1 ) = 1
IUVAR( 2 ) = 1

when it comes to the engine part everything seems broken except the UVAR/IUVAR values

NCYCLE : 1
NUMNOD : 0
TT (Time): 4.168993806020453E-005
DT1 : 4.168993806020453E-005
NUVAR : 6
NUVARI : -98

X(1,1) : 1.393955149859042E-311

V(1,1) : 1.393955149985523E-311

VR(1,1) : 1.393955150017143E-311

Am i missing something, i have been struggling the last few days with this issue and cant think of anything else to be honest.

Thank you,

Hi,

Like this, it will be difficult to assist.

Would you be able to share:

• The dll with a validation model?
• The fortran routine (so that we can try to compile them on our side)?

Best regards
