change maximum allowed photon pathlength

[AptGaurav]

Hi,

I wanted to change the maximum pathlength allowed by photons, how do I do that in the infile code?

@AptGaurav sorry for the delay in responding, we are in the process of transitioning our discussions from Google over here to GitHub discussions and we missed the notification for this.

@hayakawa16 are you able to assist with this?

Hi,

Unfortunately it is not possible to do by editing the infile. The source code needs to be modified. In the file vts/MonteCarlo/Photon.cs we have the line of code:
MaxHistoryPts = 300000;
For a intercollision mean free path of [1/(5/mm)] typical in biological tissue, this results in 60000 mm. If your application needs this limit increased, then you would need to clone a copy of our source, edit this number and rebuild. For directions on how to do this please refer to this page: https://github.com/VirtualPhotonics/VTS/wiki
On the right hand panel there is a section titled "Getting Started with the Code" with links for Linux, MacOS and Windows.

Let me know if you have further questions.
Carole
