i everyone,
I am UG student of Mechanical Engineering. I am a new user of Abaqus and currently working on co-simulation for my final year project. Actually what I am doing is prediction of heat transfer due to fluid flow in a tube of known diameter across which air is flowing, also called as conjugate heat transfer.
I created model in Abaqus/standard named Tube, created part as Tube
Assigned material properties
Created step "Dynamic, temp-disp, Explicit"
Defined inner surface of tube for interaction named FSI
Completed all requirements up to Boundary conditions. I gave disp/rotation Boundry condition(U1=U2=U3=0) at one end of tube.
Similarly created model in Abaqus/CFD named Fluid, created part as water
Created step "Flow" with energy equation on
Defined boundary conditions,
BC-1: I gave fluid velocity at inlet conditions v3=-0.58 m/s(along the length of tube) and Temp= 423K
BC-2: outlet conditions P= 0
I defined coupling schemes, controls, time increments for CFD Model.
** Interaction: FISI
*Co-simulation, name=FSI, controls=FSI_Ctrls, program=MULTIPHYSICS
*Co-simulation Region, import, type=SURFACEFSI, TEMP
*Co-simulation Region, export, type=SURFACEFSI, HFL
*Co-simulation Controls, name=FSI_Ctrls, coupling scheme=gauss-seidel, time incrementation=subcycle, time marks=yes, step size=export, scheme modifier=lag
but when I run analysis it gives error
in keyword *CO-SIMULATIONREGION, file "Co-execution-Z-Fluid.inp", line 2914: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): co-simulation
in keyword *CO-SIMULATIONREGION, file "Co-execution-Z-Fluid.inp", line 2918: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): co-simulation
I have attached the jpeg of input files how they look before and after running the analysis as it changes the commands sequence..
Kindly guide me how can I get rid of this error as I think it is last hindrance towards completion of my project.
Regards,
Ahsan.
