// XD_CONT gravity) of dom domain and minimum distance between this point and boundaries (specified bords) that user
// XD_CONT specifies in data file (typically, those associated to walls). A field Distance_paroi is available to post
// XD_CONT process the distance to the wall.
// XD attr dom ref_domaine dom REQ Name of domain.

// XD attr format chaine(into=["binaire","formatte"]) format REQ Value for format may be binaire (a binary file
// XD_CONT Wall_length.xyz is written) or formatte (moreover, a formatted file Wall_length_formatted.xyz is written).
