Hi there, I have to resume a crashed flip simulation. I cached out the .sim files directly. My simulation crashed at $SF 60. My question is the following: When I load $SF 50 from my cache as the initial state in the dopnet and adjust the output range, do I need to start the new output at $SF 50 or $SF 51. I would assume that $SF 51 would be correct since I load $SF 50 as the initial state and continue the solve from there. What makes me a bit nervous is that when I compare the filesizes from the crashed solve and the continued solve the sizes for corresponding frames are varying - shouldn't I get the exact same solve when continuing the simulation via loading an initial state? Am I missing something else? Any hint much appreciated!
Lucy Coleclough posted a topic in General Houdini QuestionsHi Guys I have a fairly high res flip sim (by student standards, about 3 gig per frame) and I needed to cache it out as a .sim to utilise checkpoints I need to read this simulation in using playback simulation on the dopnet and a dop IO node with the flip presets in order to pull in the velocity fields for a whitewater sim, however when I do this the computer gets stuck on the first frame I load in. My only current solution is to go through every frame, unticking and reticking the playback simulation button which would take me 2 minutes of load time per frame for 432 frames. An alternative I've considered is the Houdini python module however I am not familiar with this and don't know if the required functions exist. Please could someone with more knowledge on this tell me if this is possible in the python module or whether there is an alternate solution such as a way to pull velocity fields from a .sim cache Thanks George
Hi, I am doing a smoke sim. The sim is too large and so I can't simulate the entire sim in one go. I had checked the checkpoint option and gave a valid path to save the checkpoints files then simed half of the simulation and had closed houdini. I want to sim the rest of the simulation but where do I put the .sim files that are generated by the checkpoint so that the sim runs from a certain frame and not from frame 1 all over again?
