Acceleration Tabular Data

[JSN86]

Hello everybody

I need to execute a drop test on ansys workbench, and for that I need to add an acceleration curve (AKA crash pulse). I inserted a acceleration object in the workbench tree, set my coordinate system, and define the acceleration by components, and proceed to add the tabular data of time vs acceleration [m/s^2] on the tabular data spreadsheet, by copying the values from an excel file. It seems that everything is set up properly but the object still displays a question mark next to it, and highlights in yellow the components of the acceleration with the option to set them to constant or function, which in any case erases the values currently in the cells.
I find this very strange, because shouldn't time vs accel tabular data be enough to define it?

Anyone knows how to solve this?

Thanks in advance

I believe you need to edit the 'Analysis Settings' of your Model to include the correct number of time-steps as in your acceleration table.

Hope that helps,

Well Ian, at first the suggestion of setting the number of time steps equal to the steps on the acceleration table seemed to help, however with a deeper search on google I found out that Explicit Dynamics "does not support tabular data to specify the magnitude or components of Accelerations or Line Pressures".

Thanks for the help tough ...
