Some models are so \"difficult\", that I would like to have only a fire calculation to keep things simple.\r\n\r\nSo, my feature request is as follows (if it is possible): Add a parameter to an the &OBST keyword, which allows only Smokeview to show the OBST, but FDS would not consider it for calculation. So, it would be helpful if I could use all the parameters for an OBST, like TRANSPARENCY or SURF_ID, or whatever, to model an OBST and only add an additional parameter, like \"SMOKEVIEW_ONLY\", so that the OBST is written to the SMV-file, but not considered in the calculation (this means smoke, heat, velocity, radiation, ... will move through this OBST, and it has no influence of the calucated result). This means I do not need any \"EVACUATION\" commands in the file.\r\n\r\nIt would be great, if this would be possible. If you have some other ideas to realize this, feel free to post...\r\n\r\nRegards from Germany\r\nChristian"},"comment":{"url":"https://api.github.com/repos/firemodels/fds-smv/issues/comments/234048781","html_url":"https://github.com/firemodels/fds-smv/issues/4096#issuecomment-234048781","issue_url":"https://api.github.com/repos/firemodels/fds-smv/issues/4096","id":234048781,"user":{"login":"mcgratta","id":11333911,"avatar_url":"https://avatars.githubusercontent.com/u/11333911?v=3","gravatar_id":"","url":"https://api.github.com/users/mcgratta","html_url":"https://github.com/mcgratta","followers_url":"https://api.github.com/users/mcgratta/followers","following_url":"https://api.github.com/users/mcgratta/following{/other_user}","gists_url":"https://api.github.com/users/mcgratta/gists{/gist_id}","starred_url":"https://api.github.com/users/mcgratta/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mcgratta/subscriptions","organizations_url":"https://api.github.com/users/mcgratta/orgs","repos_url":"https://api.github.com/users/mcgratta/repos","events_url":"https://api.github.com/users/mcgratta/events{/privacy}","received_events_url":"https://api.github.com/users/mcgratta/received_events","type":"User","site_admin":false},"created_at":"2016-07-20T19:03:37Z","updated_at":"2016-07-20T19:03:37Z","body":"This is tricky because FDS cannot just ignore an `OBST`. It must read and process the OBST along with all the others and then pass the information about the `OBST` to the .smv file. Then we would have to put `CYCLE` commands in all the loops that work with `OBST`. But here's a hack, and let me know if it works. You can create the `OBST` that you want to ignore, and give each one a `DEVC_ID` like this:\r\n```\r\n&OBST XB=..., DEVC_ID='timer' /\r\n&DEVC ID='timer', QUANTITY='TIME', SETPOINT=0., INITAL_STATE=.TRUE. /\r\n```\r\nYou can use the same `DEVC_ID` for all `OBST` lines you want to ignore. The obstruction should disappear at the start of the simulation and never return. Now, edit the `.smv` file. Look for the string `HIDE_OBST` and change the time to a large value. Now Smokeview should draw the obstruction even though FDS ignored it. \r\n\r\nLet me know if this works. "}}
