Co-simulation error

[srimanishreddy]

hello all,

I have modeled a Fluid domain to conduct FSI simulation. In the co-execution, I had momentum convergence and the element deformation errors.

To rectify this, I edited the keywords of the Fluid domain to include FSI controls.

After the data check Abaqus CFD aborts with the error:

in keyword *CO-SIMULATIONREGION, file "co-sim_keywordedit_step1_FSI-Fluid_domain.inp", line 45607: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): co-simulation

in keyword *CO-SIMULATIONREGION, file "co-sim_keywordedit_step1_FSI-Fluid_domain.inp", line 45610: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s): co-simulation

.inp error section for the Fluid domain is as below:

Can someone help me with some hint understand why this occurs?

Place the *Control commands somewhere else, but not within the Co-Simulation block.
