Nodal Force Check Error in ANSYS. Thanks

[richonlinedeal]

Hello, all,

I am doing some structure (flexible pipe)-fluid coupling using ANSYS and CFX. After I set up the structure part of problem in ANSYS Prep7, I check the load definition by :List->Load->Force->On All Nodes, and find there are some non-zero values shown (under both Real & Imaginary)for each node. However,I only defined some nodal displacement constraint, and did not define force load for any node. Could anybody here comment what these numbers mean? Reaction force? Or some mistake I made? Thanks a lot.

Hi,
does your structural part come from a previous fluid analysis in CFX? If so, possibly some load info has been stored within the model (only a guess: I don't have CFX so I don't know how it works). Or you may have defined a load on a geometrical entity (line, keypoint,...) and then issued a SBCTRAN for some reason (or had the program do it automatically, for example by launching a partial solution).

Thanks cbrn.

I guess you are right: the force load may come from the CFX part as I solve the fluids part first.
