private double |
b
The values of the boundary conditions |
private double[][] |
BCMatrix

Constructor Summary | |
Border3(MeshBorder e,
double aa,
double bb)
|
Method Summary | |
void |
calcBCondition()
Computes the boundary conditions and modifies the vector and the matrix to take boundary conditions of the first type into account, unlike the mehod described in the book, the modifications due to boundary confitions of the first type are computes at the element level and not at the end |
double |
geta()
Returns the coefficient a of the boundary condition |
double |
getb()
Returns the coefficient a of the boundary condition |
void |
seta(double aa)
Sets the coefficient a to aa |
void |
setb(double bb)
Sets the coefficient b to bb |
java.lang.String |
toString()
Returns a description of the border, ie its global number and those of its nodes |
java.lang.String |
toString2()
Returns only the global number |
