check out MX linux 19, super easy 5 mins install and it's solid.

You can also use and expression with ifs and create the filepath based on the switch $HIP/geo/`ifs(ch("../switch1/input"),"A","B")`.$F4.bgeo.sc returns A.0001.bgeo.sc or B.0001.bgeo.sc conditional_output.hiplc

well, cron+rsync... https://serverfault.com/questions/189499/rsync-to-create-directory-based-on-date

cron job?

you can also duplicate your DOPnet and disable everything related to vel since you copy it from the loweres sim eg: forces/buoyancy/vel advection/projection then just copy "compute turb","ramp turbscale","primary noise" from the gasUpres solver and you get a sparse upres. https://vimeo.com/388758247

inside the GasCombustion DOP, have a look at the "temp_to_burn" node there is a "constant" parameter, that's where your ignition temperature goes. you'll have to replace that node with a custom wrangle for example...
-
you should watch this, it's still relevant: https://www.sidefx.com/tutorials/h13-masterclass-bullet/
-
of cource, you're using volume collision (blue) that's not going to work. Bullet uses Packed primitives only.
-
you can use the name attribute to filter out objects to activate in the pop wrangle: eg: if your collider is named "collider" if(s@name!="collider"){ // activate the other pieces }
-
not sure what the dark blue object is but it should also be a convex packed primitive object.
-
I had a look at your HIP file, there was a few issues. - the left side of the body didn't have a name attribute, same of the new faces from the PolyExtrude - convex decomposition won't be consistent on animated geometry a much better way is to create all your pieces on frame 1 and pointdeform them to transfer the animation. for the activation, you can use a wrangle in DOPs and lookup your pointcloud directly. girl_fracture_05_convex_decomposition2.hiplc hope that makes sense.
-
You should use convex pieces with Bullet, the convex decomposition SOP can help with that. convex pieces are slow and (very) buggy.

In a smoke simulation, how can I change the velocity over time?

// simple drag v@vel*=clamp(1-chf("drag"),0,1); -
you can do that with some Python on a shelf tool, and assign a keyboard shortcut: ipr=hou.ui.paneTabOfType(hou.paneTabType.IPRViewer) if ipr.isPaused(): ipr.resumeRender() else: ipr.pauseRender() also usefull, ipr.startRender() ipr.killRender()

you need to pass P through your if block if_else_sops_dops2.hipnc or use a wrangle, much simpler and cleaner. if(@ptnum>1444)@P.y+=3;
