Hello everybody,
I want to move the upper wall (in negative y-direction) of a frustum of pyramid (first picture). I do this with the option Dynamic Mesh -> Layering -> Rigid Body and use a profile file to specify the direction and velocity of the movement. My question is, how i can shrink the moved wall also in x- and y- direction too, so that the wall doesn't look like in the second picture below but rather behave like the fluid level of a tank. An example for an profile file can looks like this: mvx.prof ++++++++++++++++++++++++++++++++++ ((mvx3 point 7) (time 0.0 2.0 10.0 12.0 14.0 22.0 24.0) (v_y 0.0 -0.03 -0.03 0.0 0.03 0.03 0) ) ++++++++++++++++++++++++++++++++++ First picture https://www.dropbox.com/s/4ksxx46y6l...all01.jpg?dl=0 Second picture https://www.dropbox.com/s/07ldp6838c...all02.jpg?dl=0 |

Ok, found out that if you want to move and deform a mesh you have to use a udf.
Dynamic Mesh Define Macros are described here: https://www.sharcnet.ca/Software/Flu...udf/node75.htm In combination with the time dependency you've to use the time-dependent macros: https://www.sharcnet.ca/Software/Flu...df/node105.htm Regards. |
