[FLASH-USERS] Particles Unit

[Norbert Flocke]

Hi Ryunosuke,

As I mentioned before, running particles unit and laser unit together can 
create problems, as both use the grid particles unit. However, the grid 
particles unit uses fixed precompiled dimensions for its buffer arrays. 
Please have a look at the gr_ptInit.F90 code and the comments there.
The error message you are seeing is a consequence of the fixed buffer 
dimensions.

For a solution to this problem in your case, go to the FLASH directory:

source/physics/sourceTerms/EnergyDeposition/EnergyDepositionMain/Laser

and edit the file 'EnergyDeposition.h'. Change the RAY_ATTR_COUNT entry 
(that is currently set to 16) to 35. This will not change the laser code, 
but will make it use twice as much memory as before. If you are not using 
many laser rays in your beams this should be ok. If you are using millions 
or rays, you will see performance degradation.

Best,
Norbert

From your current Config file the Particles/localAPI directory is never reached and hence you don't have the compiled pt_interface.mod file.
