Can't add gravity #26

Closed apalazzi closed 6 years ago

apalazzi commented 6 years ago

Hi,

I'm trying to use this plugin to run MBDyn but the tutorial seems to be running a different version of the plugin and I can't figure out how to set the gravity vector.

In the tutorial https://www.youtube.com/watch?v=RKprhyOqHZM a nice windows asking for a vector shows up when Gravity is added, however all I can do is add an array of 3D drives or a template 3D drive.

Whatever I choose, I can't figure out how to add the gravitiy to the problem, can you help me?

I'm using blender 2.77, same thing with blender 2.79.

1) Inside Gravity select "New" Template Drive 2) Click Use Drive 3 (the global Z-direction), and select "New" Drive. 3) Make a Constant Drive with value of -9.8 4) OK to save Constant Drive, OK to save Template Drive, OK to save Gravity.

This follows how MBDyn specifies gravity: a 3D field aligned with the global reference frame. (In the tutorials, and earlier versions, gravity was more intuitive, but did not support the more general cases supported by MBDyn.)

Checked and it works, thanks.
