Hi,
For example, I run a simulation as below like direct shear test, I want to get the total force of cylinder in x direction, but just the part of pos_x <0(center is (0,0,0)).
Thanks
Hi Raheem,
You can use geometry force queries of contact force queries combined with a bin group. For the bin group you can create a grid or geometry bin that covers the X or X- area of the domain/geometry (see e-learning lesson 17.5 for info on the sensors - https://learn.altair.com/course/view.php?id=147)
once you have the bin setup you will need to turn on all geometry and/or all geometry-particle contacts as this info isn't queried by default.
Once oyu have this you can export or plot the data within the bin selection, in the screenshot below I am exporting total force in the X direction on the Chute geometry but only the parts of the chute geometry that are inside the Geometry Bin Selection:
You can do the same for particle-geometry contacts but you have to add Normal and Tangential force queries separately. Geometry force is the sum of the contact forces so the contact force is the raw data that has been applied to the geometry.
Advantage of using contact force is that it is queried based on the contact position, geometry force is queried based on the geometry mesh, so if you have a very large geometry mesh element which is part in and part out of the bin, then it will only be considered if the Centre of Mass is inside the bin and if that is the case all forces on that element will be added, even if some of the forces are outside the bin area.
