ok, thanks for all the help I hope I made it, I will appriciate if you can give me a feedback on my work

so here a picture of the conteiner and a object (for example engine) that prouduce heat flux (section view)

so as we can see in the left side, the boundry condition i make are:

1. fixed temperutre - of 25[c] of the earth the contiener seat on (like in the video you send me of the fire)
2.  convection - on the all wales (not enclud the floor) with value of film coefficent = 50W/m^2C while temp is 35[c] this from the wind
3. Heat flux - I didnt saw the option of radiation from the sun so I saw a viedo that says that the approximate heat flux that can replace the radiation is 1000 W/m^2 so i put it on the top of the conteiner (I decided that the sun is in the middle of the sky)
4. Heat flux 2 - an approximate heat flux from the object (engine or what else) of 400 W/m^2
5. convection 2 - the holes (rectungular holes) in the walls are not forced convention so I put 35[c] and film coefficent = 10W/m^2C the convection is on the wall of the engine like in the pic
6. convection 3 - the 1 hole in the walls are forced convention (ventilator) so I put 35[c] and film coefficent = 50W/m^2C the convection is on the wall of the engine like in the pic             here image without no section view    

tThanks very much
