fortran variables describing free surface
 

I am simulating the process of laser heating powders, using heatfl for customization. The energy deposition is concerned to the free surface geometry, but manual gives limited fortran variables about free surface. Would anyone give more details, like surface orientation(normal or tangential) ? Thanks

Please send over your prepin file and details of the problem along with version of FLOW-3D you are currently using to adwaith@flow3d.com

Thanks

i think the variable "free surface elevation" is what you want. hyel is used to express the free surface elevation. however, i can't apply the hyel in my code. maybe we can have some discuss to solve the problem.
