  • Phoenix 2.2 to 3.0 confusion

    hi,

    i´ve recently installed the upgrade for max 2017 although i cannot seem to check if its loaded correctly.

    i´d like to use the object morph feature (attraction force under the object right click phoenix fd options)

    the problem is the "right click phxd option" dialog is missing features from the screencap description online.
    i dont have the same options, just some of them.

    the example scene is also not working. i hit simulate and the blobs of paint remain still as if nothing is attracting them.

    already wrote to support but recieved no reply.
    i´d really appreciate some help.

    Hello,

    Can you show me which options are missing from your PhoenixFD menu? Can you add a screenshot?

    There is no attraction force in the right-click menu. The BodyForce you are referring to is a separate node that is added from the PhoenixFD Helper Tab.

    To check which version of Phoenix you have installed you can go to the Simulation rollout of your Simulator and press the About button.

      thanks for the reply. attached are my screencap and the only reference to the attraction i could find online.
      apparently things changed in the v3.

      i´d like to do a scene very similar to the example scene https://vimeo.com/92918518

        the morphing concept of 3.0 was changed, the old simulator had global attraction force, that appeared to be not quite convenient, it required animated geometry in order to do the morphing.
        in version 3.0 the force is per object, and you just have to create two (or more) objects, animating the force strength switching it on/off
        the correct per object settings of 3.0 are the ones shown in the first image, there must be wetting and initial fill up

          Ah, indeed. You are using v3 now.

          We have a sample scene how this is done using the BodyForce. The scene can be found here - https://docs.chaosgroup.com/display/...Example+Scenes

            thank you both.

            i have managed to test it out. my mistake for not noticing the updated scene file.

            does not seem as if it will work for the animation im working on.
            im dealing with typography with fairly thin geometry. the letters are extruded, much like if one would write something with a ketchup bottle, so there is not much volume.

            the problem is:
            - i need lots of detail to get any sort of definition. even with a dense grid, the resulting object mesh is way to thick and obliterates the form underneath. could maybe flip solver be better suited?
            - the shape cannot seem to settle at all. not sure if its due to normals being too close.

            i´d post a screenshot but its project being developed...

              Hey,

              I'm afraid if the letters need to be thin, the only thing you can do is to use higher resolution. This would help the settling issue as well, along with the 'Internal damp' and 'Damp min velocity' parameters that you have to increase and decrease respectively.

              Hope this helps, please ping us if you are still having issues.

                thanks svetlin,

                i was afraid of that.
                infact the whole sentence is actually one continuous mesh so its not even possible to parse it into smaller bits and have the thickness relatively larger that way.
                most likely i will have to pursue some other method though. will surely do some further tests with phx and report back.

                best,
