function [b2,n2,b1,n1]=basis1d1(zref,zdes) |

----------------------------------------------------------------------- |

| 15 |
purpose: This subroutine evaluates the value of the basis functions |
|---|
| 16 |
alive on a 1-D linear element at a point |
|---|
| 17 |
|
|---|
| 18 |
restrictions: Applicable only for 1-D linear elements |
|---|
| 19 |
|
|---|
| 20 |
inputs: nn is the number of entries in the reference z array |
|---|
| 21 |
zref(nn) is the 1-D array containing the reference z array |
|---|
| 22 |
NOTE: zref must increase from zref(1) to zref(nn) |
|---|
| 23 |
zdes is the z value at which the basis functions are desired |
|---|
| 24 |
|
|---|
| 25 |
outputs: n1 is the reference node immediately below zdes |
|---|
| 26 |
b1 is the value of the n1's basis function at zdes |
|---|
| 27 |
n2 is the reference node immediately above zdes |
|---|
| 28 |
b2 is the value of the n2's basis function at zdes |
|---|
| 29 |
|
|---|
| 30 |
notes: zdes<zref(1) => n1=nn,b1=0.0,n2=1,b2=1.0 |
|---|
| 31 |
zdes>zref(nn) => n1=nn,b1=1.0,n2=1,b2=0.0 |
