I'm adding collision to icolagrangianfoam. I am using the spray class as a referrence to how to do this but when i try to make my ptfoam i get an error as follows

SOURCE_DIR=.

this seems to be related to *this operator as in incompressiblecloud.c or in spray class as in spray.c

collisionModel_
(
collisionModel::New
(
sprayProperties_,
*this,
rndGen_
)
),


i have two questions i hope you can help me with

1 what exactly is *this and how does it work?

2 how do i get it to read newcollision.c so i can use a modeified o'rourkes model or modified trajectory model instead of the normal collision model

thanks
