jakigui Posted August 2, 2015 Share Posted August 2, 2015 Guys I am doing some rnd on fracturing and came across this issue. I got 1 box fractured and I want each sides of da box to be active and middle part to be inactive. I used a sphere then connect it to a group(points) then used attr create. it worked perfectly. But when i do da same to the other side it doesnt work. Can anyone help me on this? Thanks!!!! multiple _active_regions.hipnc Quote Link to comment Share on other sites More sharing options...
timfagan Posted August 3, 2015 Share Posted August 3, 2015 (edited) I've edited your file to add the extra active region on the left side. I think you had the right idea you just need to use the union with existing in the second group node. multiple _active_regions_edited.hipnc Edited August 3, 2015 by kayman Quote Link to comment Share on other sites More sharing options...
timfagan Posted August 3, 2015 Share Posted August 3, 2015 (edited) I think a cleaner way to set active object though is within the dop network. The second image shows the adjusted setup. The extra sop solver lets you define the active region with the help of the group and attribute wrangle, you just need to set the objects to initially be static. And just use an extra group node to get extra active regions. multiple _active_regions_edited2.hipnc Edited August 3, 2015 by kayman Quote Link to comment Share on other sites More sharing options...

timfagan Posted August 3, 2015 Share Posted August 3, 2015 Yeah to get the sphere editable in the SOP solver you need to use the correct selector tool. Not sure what it's called but here's a picture. The import dops node etc can all be set up automatically for you by selecting the shelf tool when you make your rigid body. I put a note in the wall object to show when I used it.

jakigui Posted August 3, 2015 Author Share Posted August 3, 2015 (edited) sorry it is not abt the dop netowrk it is abt da sop solver. I can c green part here but when i sim it is not correct. It doesnt take da active region. hip file i uploaded exactly like this. Edited August 3, 2015 by jakigui Quote Link to comment Share on other sites More sharing options...
timfagan Posted August 3, 2015 Share Posted August 3, 2015 (edited) You need to change the box object from active to static in the initial object type selector. Also helping you would be easier if you could take an extra moment to write a bit more clearly. Edited August 3, 2015 by kayman Quote Link to comment Share on other sites More sharing options...
