c. FORTRAN Interface

Mesh Object attribute data are accessed through a set of subroutines. An example of accessing an existing Mesh Object and creating a new mesh object is given in Section IV.d; that example should be used as a template when operating with Mesh Objects. The subroutine set includes: cmo_get_name: retrieve active mesh object name cmo_set_name: set active mesh object name cmo_get_info:retrieve mesh object pointer cmo_get_intinfo: retrieve mesh object integer data cmo_get_attinfo: retrieve mesh real or character data cmo_set_info: set mesh object integer data cmo_set_attinfo: set mesh real or character data cmo_newlen: adjust the lengths of mesh object data based on the values of number of nodes and number of elements which are stored as integer mesh object attributes (nnodes, nelements)

Only data from the active Mesh Object may be retrieved; calling cmo_set_name will make the referenced Mesh Object active. Scalar quantities are retrieved and stored using cmo_get_intinfo, cmo_get_attinfo,  and cmo_set_info. Vector quantities are referred to by their pointers. The length of the vectors is calculated internal to LaGriT based on the values of the scalar mesh object attributes. Memory allocation for a new mesh object or for a mesh object which will grow in size is accommodated by first setting the appropriate scalars for the Mesh Object by using  cmo_set_intinfo with the new number of elements and/or nodes and then callingcmo_newlen. These two steps must be taken before adding to the size of a Mesh Object.

Mesh object parameters are retrieved with thecmo_get_attparam subroutine.

See IV.e.2 for a list of  mesh object subroutines .
