Hi all,

 

How can I export drag force on a surface to Abaqus or nastran?

To use drag force as force/loading to strength analysis.

 

Or how to export drag force to Tecplot file (*.tpl or *.dat)?

 

Thanks

    1. Activate surface nodal output using

        Model > Surface 'Name' > Nodal Time Step Frequency

     

    2. Export data using AcuOut or AcuTrans to x,y,z, traction_X, traction_Y, traction_Z

       Output format = Table > Surface Output (Nodal) > Surface Name > coordinates, traction

       This creates .osf (ASCII text) file coordinates and traction forces.

    I stand corrected.

    Traction exported by Surface Nodal Output would be stresses. Since you can also export nodal area as another quantity, it should be easy to do the multiplication done for getting forces.

    Hi ydigit,

     

    Follow Output format = Table > Surface Output (Nodal) > Surface Name..

    But no variables show up. And this warning come out ''acuTranse cannot be called, as the Time Steps is not available for this problem''

    Is there any setting needed before can use above method?

    Thanks

    Have you enabled the Surface Nodal output? Please upload the .INP file.
