DATA SET 14. DIRICHLET BOUNDARY CONDITIONS

There are three groups of data in this data set for the boundary profiles, the global Dirichlet node numbers, and the boundary profiles assigned to Dirichlet boundary nodes, respectively. This data set is required if and only NDNP > 0.

(a) Dirichlet-head profiles - There are NDPR records in this subset. The number of lines in each record depends on NDDP. The I-th (I = 1, 2, ..., NDPR) record, in FREE FORMAT, contains the following variables:

1. THDBF(1,I) = Time of the first data point in the I-th profile, (T).

2. HDBF(1,I) = Total head of the first data point in the I-th profile, (L).

3. THDBF(2,I) = Time of the second data point in the I-th profile, (T).

4. HDBF(2,I) = Total head of the second data point in the I-th profile, (L).

Up to NDDP data points.

(b) Dirichlet nodes - One record is needed for this subset. The number of lines in this record depends on NDNP. This record, in free format, contains the following variables:

1. NPDB(1) = Global node number of the first Dirichlet node.

2. NPDB(2) = Global node number of the second Dirichlet node.

Up to NDNP data points.

(c) Type of Total Head Profiles of Dirichlet Nodes: Normally one record per Dirichlet node, i. e. a total of NDNP records are required. However, if the Dirichlet nodes appear in regular patterns, automatic generation may be made. Note that this subset must be repeated NDF times to cover all of the pore regions. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables.

1. NI = Compressed Dirichlet node number of the first node in the sequence.

2. NSEQ = NSEQ subsequent Dirichlet nodes will be generated automatically.

3. NAD = Increment of NI for each of the NSEQ nodes.

4. NITYP = Type of total head profile for node NI and NSEQ subsequent nodes.

5. NTYPAD = Increment of NITYP for each of the NSEQ subsequent nodes.

NOTE: A line with 5 0's must be used to signal the end of this subset.
