Dear Krapf,
Thanks for the reply. It is helpfull. But I am facing another problem related to 'phase compression factor'
Quote:
--> FOAM FATAL ERROR: (openfoam-2012)
Phase compression factor (cAlpha) not found for : (air and liquid)
Please check my code and let me know if any data missing.
Please help me to resolve this problem.

(0.001 (0.0012 0.000101 0.0001))

);
0 and 0.001 are time and the numbers in parentheses are coordinates. thus no need to define velocity.

(3) From the original LaserDTRM post (https://www.openfoam.com/releases/op...nd-physics.php),

The laserPower (W) is a Function1 Type of entry to allow time based variation. The laser power distribution can be uniform, Gaussian or manual. When using the mode manual the total laser power output is :

Hope that helps!

hello OPFO:
Do you know how to add more than two laser(multi laser) heat sources?

In radiationProperties files ,it seems that only one laser can be specified。

Can you give me some advice on these issues?

best regards

Ni Jie
