UDXappend2Ddata(filename,p,t,u,attr_name,attr_rank,attr_shape) Apends data to a file in DX form. Only one variable can be written to the file variable must be a scalar, vector or tensor of doubles mesh data in the file must be consistent with this variable x attr_name = name of the variable (type string) attr_rank = rank of variable data (0 for scalar, 1 for vector, etc.) attr_shape = number of components of variable data (assumed 1 for scalar)
