I could able to run successfully this simulation first time. later again i compiled its throwing error "obj\Debug\ConfigExperiment.o||No such file or directory| obj\Debug\ConfigSample.o||No such file or directory|" But actually files are present in this path. Can u please help me out what's going wrong in the compilation flow |

try compile with the command: g++ main.cpp ExperimentData.cpp thermo.cpp -o zlambda -pthread -std=c++11 -O3 or you can download compiled windows bin version from this repository: bin/0.73.0-latest/zlambda0.73.0-x64Win.zip |

Hi Rafal,
Thanks for the reply. I could able to resolve the compilation issues.
but i am unable to generate the heat map after the execution.
Could you please help me to generate the heat map and correct the input of
ConfigExperiment and ConfigSample?
attaching the both configExperiment and ConfigSample.
My requirement is to irradiate the gold sample with different laser power
for 3 seconds and see the temperature increase in the work piece.
Below are the parameters.
The gold work piece :
z axis : 2mm
x axis : 5mm
y axis : 5mm
Laser Wavelength : 450nm
Laser Power : 40W
Continuous Exposure for 3 seconds. no pulse width modulation.
Laser Beam : 2x2mm area or 2mm radius
Velocity is Zero : no range scanning.

Dear Venkatesh Raju
Thank you for your interest in our program.
Unfortunately, this program does not perform calculations for
non-transparent materials.
It was invented for transparent materials (for example, glass) and for
pulsed beam lasers.
With greetings
