DOP TimeScale vs Solver ScaleTime


Recommended Posts

Hello !


I'm trying to understand the difference between Time scaling a Sim at DOP level vs Solver level.

Basically i understood that DOP timescale will act on everything inside it (substepping every solver accordingly) whereas Solver scale time will only influence 'this' solver locally.


This idea in mind, i tried to get similar result on a basic Flip Sim with both method (setting 0.5 for dop timeScale  or for flip solver Scale Time).

After lot's of test (messing with substepping, CFL etc), i was not able to get similar result and can't understand why :/ !


Here is the simplistic scene with only the timescale and scaletime modified. Can you get both sim to correspond exactly (get the same collision behaviour)?

Or is there any reason both sim can't be identical?


Thanks in advance!
