i read every toturials about thermal comfort

i model a room with an occupant,i tried to inter a 0.1 m/s velocity to the room with boundry condition on window

the first few times i get the result but now it show temperature without change inside of the room and the plane result doesnt work anymore,i tried to reinstall it but nothing happend,i really need help bcuz i need those result for my thesis

Try this, right click anywhere and selct "Show all". Then go create your plane. Then go to View >> Visual style and select as outline. You should have your results.

tanx OmkarJ 

it did worked but what about the temperature result in iteration

sometimes it worked and sometimes not

I do not understand your question. Can you post your iteration graphs and then elaborate the question?

this is my iteration bar and my model

in this model the temperature doesnt come inside the model through that window,but it should be doing that and in some solve iterations it did that , but i really dont know why its not working most of the times

Try this, on the buttons you see towards the right side of your graphs, click on the button that says "All" and choose temperature. Do you see anything?

i see that but why its leaner all the time?

Again, you didn't post the image so I can't know your definition of linear :smileyhappy:

The reason for its flatness may be that that there is hardly any change in it over the iterations, meaning, probably the initial guess was too good for the temperature hence it didn't need significant changes during iterations and there aren't large temperature differences in the room so the average temperature didn't change drastically over the region. Also, you may want run for more iterations until your pressure, velocity and turbulence numerics also gets flatter.
