Thanks for the updat @chriswmackey . So if I assign a grid in Hb and convert to osm, will that grid not transfered ? For the recipie issue I still didnt get it ,my model is valid and runs successfully locally! Is there a way I could run it on web !

@chriswmackey I again tried the recipe and its failing again. [Capture] Pollination Cloud App The All-In-One Platform for Environmental Building Simulation

[image] asisnath: So if I assign a grid in Hb and convert to osm, will that grid not transfered ? Correct. There is no way to store a sensor grid in the OSM. For the other issue, this appears to be different than my original explanation as the run is failing. @antoinedao or @mostapha , do yo…

FYI, @asisnath . If that node is running out of memory, you should be able to get it to succeed by running a shorter run period. You said that you had no issues running it locally, right?

@chriswmackey Thanks for the update. I will give a try for a particular month.

Looking at the the files going into that node, I’m pretty sure we are running out of memory. The SQLite file coming out of E+ is 4 GB: [image] … and we’re probably loading half of this data into the node to be able to perform the longwave MRT calculation. Running the simulation for a month will …

@chriswmackey . I gave sensor points for 2 rooms only rather than 600 zones. I may be wrong but though I am using 2 rooms for sensor grid it still performs energy simulation for 600 rooms. I will run for a month in an hour and post the update.

[image] asisnath: I gave sensor points for 2 rooms only rather than 600 zones So is there a reason why you need all of the other rooms of the model? Can’t you just put those two rooms that you care about into their own model and run the recipe with that? The recipe is forced to run an energy …

What I was thiking @chriswmackey is that as this was a multizone model and each zone will be effected by adjacent zones thermal condition, it need to have energy simulation of total 600 rooms. If I only put individual rooms than it would be like simulating a shoebox model. I may be wrong but for t…

[image] asisnath: it need to have energy simulation of total 600 rooms. If I only put individual rooms than it would be like simulating a shoebox model If all the spaces are conditioned and they have a similar usage pattern (e.g. similar occupancy schedule, loads) and facing a similar directi…

[image] chriswmackey: But I think the only way we’ll get the original large simulation to succeed is by being able to allocate larger resources to this particular node since I think I have gotten this task in the recipe to be as optimized as possible. This is just the pinch point of the recipe. …

This is an old topic but I just wanted to post an update that models in this scale and even larger should run on Pollination with no issues after this recent improvements.
