for all the nfrlag boundary zones previously identified, a particle boundary condition type is given. The categories of particle boundary condition types are marked out by the key words ientrl, isortl, irebol, idepo1, idepo2, iencrl.

if iusclb(izone) = ientrl, izone is a particle injection zone. For each particle class associated with this zone, information must be provided (see below). If a particle trajectory may cross an injection zone, then this particle leaves the calculation domain. - if iusclb(izone) = isortl, the particles interacting with the zone izone permanently exit the calculation domain. - if iusclb(izone) = irebol, the particles undergo an elastic rebound on the boundary zone izone. - if iusclb(izone) = idepo1, the particles settle permanently on the boundary zone izone. These particles leave the calculation domain and are permanently erased from the calculation - if iusclb(izone) = idepo2, the particles settle definitevely on the boundary zone izone and they are kept in the calculation
if iusclb(izone) = idepo2, the particles settle permanently on the boundary zone izone and they are kept in the calculation domain: the particles do not disappear after touching the boundary zone. However, using idepo2 type zones necessitates more memory than using idepo1 type zones.
if iusclb(izone) = iencrl, the particles which are coal particles (if iphyla = 2) can become fouled up on the zone izone. The slagging is a idepo1 type deposit of the coal particle if a certain criterion is respected. Otherwise, the coal particle rebounds (irebol type behaviour). This boundary condition type is available if iencra = 1. A limit temperature tprenc, a critical viscosity visref and the coal composition in mineral matters must be given in the subroutine uslag1.

integer, dimension(:,:,:), allocatable iuslag

Some pieces of information must be given for each particle class associated with an injection zone. The first part consists in integers contained in the array iuslag. There are at the most ndlaim integers. This data must be provided for each class iclas and each particle injection zone izone. They are marked out by means of "pointers":

iuslag(iclas,izone,ijnbp): number of particles to inject in the calculation domain per class and per zone.
iuslag(iclas,izone,ijfre): injection period (expressed in number of time steps). If the period is null, then there is injection only at the first absolute Lagrangian time step (including the restart calculations).
iuslag(iclas,izone,ijuvw): type of velocity condition:
if iuslag(iclas,izone,ijuvw) = 1, the particle velocity vector is imposed, and its components must be given in the array ruslag (see below).
if iuslag(iclas,izone,ijuvw) = 0, the particle velocity is imposed perpendicular to the injection boundary face and with the norm ruslag(iclas,izone,iuno).
if iuslag(iclas,izone,ijuvw) = -1, the particle injection velocity is equal to the fluid velocity at the center of the cell neighboring the injection boundary face.
iuslag(iclas,izone,inuchl): when the particles are coal particles (iphyla = 2), this part of the array contains the coal index-number, between 1 and ncharb (defined by the user in the thermochemical file dp_FCP, with ncharb <= ncharm = 3).

By default, the number of particle classes is zero. The maximum number of classes is nflagm (parameter stored in lagpar, whose default value is 20).
