I run this model for an half-period and intend to set the output obtained (say test.chk) as the "Initial Condition" in the subsequent model. To achieve this, I execute the following command:mpirun -np 28 FieldConvert test.xml test.chk test.fldThen, in the XML file (say new.xml), I define<FUNCTION NAME="InitialConditions"><F FILE="test.fld"></FUNCTION>However, when I checked the wall shear stress (wss) outputs, I noticed that the second run may ignore the initial condition (test.fld). What might be causing this issue? What is the proper way to define a restart file? What are the possible solutions (e.g., if there is any other file format that I can use as an initial condition to restart the model, would you please explain how to obtain this format)? Attached is an example of the wall shear stress signal (x-component) signal. This curve should be sinusoidal when the flow is laminar. One can see in the red-circled area that the flow behaves as the model starts from the very beginning (as in the blue-circled area) like there is no initial condition file. Thank you very much for your time and intention.Best regards,Selman BaysalR. A. in HydraulicsDept. of Civil Eng'gÇanakkale Onsekiz Mart University--ITU Civil Eng., BSc.ITU Coastal Sci. & Eng., MSc.
