Title: 3D Smoke and exhaust fan
Post by: kp12 on April 20, 2020, 11:26:17 am
Hi everyone,

i am new to Pyrosim and started using for university final year project. There are some problems on simulation in my project.

1) I try to run a simulation and the fire cannot emit smoke ( i can see the temperature of the fire from the 2D slices but the visibility did not change and the 3D smoke did not show)

2) The exhaust fan seems does not work

I really need help with this and i would be grateful if anyone can help.

The reaction you are using has a value of zero for the soot yield. Change that to 0.1.

2) The exhaust fan seems does not work


Set the Vent Endpoint on the Node Type to "in" and "out".
