Bi-sinusoidal pressure on plate

Bi-sinusoidal pressure on plate

Bi-sinusoidal pressure on plate

Good afternoon to everybody,

I'm needing some help on applying a bi-sinusoidal static structural load on a square plate, like in the image.
I tryied to find something useful on the web but I only got Transient analysis type of help.
Could you give me some tips on the macro/apdl code for this?

Thanks in advance

RE: Bi-sinusoidal pressure on plate

Thank you, but I'm actually using MAPDL.
This is the plotted function in Wolfram Alpha.

RE: Bi-sinusoidal pressure on plate

Got it! A friend helped me. This is the APDL command to apply bi-sinusoidal pressure on a square plate.

RE: Bi-sinusoidal pressure on plate

Here's an example how to read your particular function from a csv file using *tread. I included also the original excel file
and the apdl command file to read the data. Please let me know if it works as intended.
