DATA SET 10. CARD INPUT FOR INITIAL OR PRE-INITIAL CONDITIONS

This data set is required only if KSTR = 1. Normally, NNP record, one record for each node, are needed. However, if a group of nodes appear in regular pattern, auto-generation is made. Each record contains the following variables:

1. NI = Global node number of the first node in the sequence.

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

3. NAD = Increment of node number for each of the NSEQ nodes.

4. HNI = Initial or pre-initial pressure head of node NI, (L).

5. HAD = Increment of initial or pre-initial head for each of the NSEQ nodes, (L).

6. HRD = 0.0.

NOTE: A line with 6 0's must be used to signal the end of this data set.

NOTE ON INITIAL CONDITIONS AND RESTARTING: The initial condition for a transient calculation may be obtained in two different ways: from card input, or steady-state calculation using a time-invariant boundary conditions that are different from those for transient computation. In the latter case a card input of the pre-initial conditions is required as the initial guess of the steady state solution.
