Hi there, I am trying to model the interaction between a tennis ball and racket. I am following instructions from an Abaqus tutorial but I am getting errors as a result of me making changes to the keyword editor (as required in the tutorial) highlighted to where the red type mark is in the attached photo is what I am trying to add but every time I submit a data check I get the following error: "in keyword *FLUIDBEHAVIOR, file "Tennis-analysis.inp", line 285: The keyword is misplaced. It can be sub option for the following keyword(s)/level(s): model" How can I Solve this? Thanks
