In this FDS example a simple radiator in a room is simulated.
1. Description
In a room with dimensions of 4 x 3 x 3 m, the radiator is simulated by modeling obstruction with a high surface temperature.
2. Mesh
The computational volume is divided into several meshes.
The meshes increase in definition as their proximity to the radiator increases.
&MESH ID='Grid 01', IJK=15, 15, 15, XB=0, 3, 0, 3, 0, 3/
&MESH ID='Grid 02', IJK=6, 30, 15, XB=3, 3.6, 0, 3, 0, 3/
&MESH ID='Grid 03', IJK=5, 60, 30, XB=4, 3.6, 0, 3, 0, 3/
3. Radiator
The radiator is simulated through different obstructions (OBST) which is assigned a surface (SURF) whose temperature is high. This is done via the TMP_FRONT command.
&OBST XB=3.8, 4, 1.8, 1.85, 0.2,1, COLOR= 'WHITE', SURF_ID='radiator' /
….
….
&OBST XB=3.8, 4, 1.9, 1.95, 0.2,1, COLOR= 'WHITE', SURF_ID='radiator' /
&SURF ID='radiator', TMP_FRONT=70. /

If this part feels a bit dense or unclear, you’re not alone—FDS has a learning curve. I offer individual lessons where I walk through the same concepts step by step, starting from the fundamentals and covering more advanced topics as needed.
I’ll share everything I’ve learned over the years, along with tools and strategies that can save you a lot of time.
4. Outputs
As outputs there are slice files that measure the speed and temperature of the air in the environment.
