C --GETALV reads the values for the requested birth/death variable and
|
||
|
|
C --returns the element state.

C --
|

|
|
C --The element is alive iff the input variable is 0.0.

C --Parameters:
|
||
|
|
C -- A - IN - the dynamic memory base array
|
||
|
|
C -- NALVAR - IN - the variable sequence number
|
||
|
|
C -- ALIVAL - IN - the value to indicate element is fully alive
|
||
|
|
C -- ISTEP - IN - the time step number
|
||
|
|
C -- LENE - IN - the cumulative element counts by element block
|
||
|
|
C -- ISEVOK - IN - the element block variable truth table;
|
||
|
|
C -- variable i of block j exists iff ISEVOK(j,i)
|
||
|
|
C -- ALIVE - OUT - true iff the element i is alive
