Detailed Description

It model an expression expr1 * expr2.

Warning: expr1 MUST be a constant expression only expr2 depend form variable, this requirement ensure linearity in the solving variable of the equations

Template Parameters

expr1
expr2

inlinestatic

Calculate the position in the cell where the mul operator is performed.

it just return the position of the staggered property in the last expression

Parameters

pos	position where we are calculating the derivative
gs	Grid info
s_pos	staggered position of the properties

inlinestatic

Calculate which colums of the Matrix are non zero.

Parameters

g_map	mapping grid
kmap	position where the multiplication is calculated
gs	Grid info
spacing	of the grid
cols	non-zero colums calculated by the function
coeff	coefficent (constant in front of the derivative)

Last element of multiplication
