help on DAA card

Hi all,

I am planning to use a DAA card from Radioss.

I have tried to use it over a plate, in that case, I am able to get the displacement of the plate.

In order to validate the DAA card, it is required to calculate the pressure on the plate which is not getting calculated.

Anyone who used this card, please guide on the same.

I am attaching RAD files for reference.

Thank you in advance.

Regards,

Sachin

Hi Sachin,

I would advise you to output external forces applied on nodes (External pressure isn't available yet):
here are the keywords that you can put in your engine file (1.rad)
/ANIM/VECT/FEXT for animation files
/H3D/NODA/FEXT for h3d files.

I hope this helps you

Hi Sachin,

You can output the contour of applied forces with the following keywords:
/H3D/NODA/FEXT
or
/ANIM/VECT/FEXT

It should be working well with DAA load or any load.
