Elmer Discussion Forum

I just change it from iterative solver to direct and it ran much quicker, obviously Linear System Solver = Direct !Iterative Linear System Direct Method = Mumps Windows version may not have Mumps, but it would have banded or umfpack. Direct may run out of memory, in which case you are stuck with the...

The default values for materials and constants in Elmer are SI units. The SI unit for distance is meters. You could work in a different unit system but you would have to change al of the constants and values supplied by Elmer. So Elmer thinks you pad area is 0.895M^2 and that you board is 10 M wide ...

Added comments in sif to explain my reasons for the changes

The form is going to create

Material 1
name="Hiperco50aA"
End

the free text will show above the end, So I do not think you need the second end in the free field

This forum "Contributed Cases" is to share resolved and solved problems. There has been frequently the need to share Elmer cases among the users. This forum called "Contributed Cases" might provide a simple way for sharing the cases. To maximize the benefits of the forum the foll...

This is covered in Chapter 9.2

In the solver section you have to have Apply Contact BCs = Logical True to apply contact conditions In the boundary conditions you have to define the contact conditions Boundary Condition 2 Name = "leading" Target Boundaries(1) = 8 Force 1 = Variable Time Real 0.0 100 0.08 100 0.0801 0 0.4...

The only way I could get it to make a difference was

Body Force 1
Name = "Divergence Damping"
Pressure = Variable Coordinate 1, Coordinate 2
Real MATC "20e-6 * 10^((20 * log(sqrt(tx(0)^2 + tx(1)^2))/log(10) + 11) / 20)"
End

Boundary Condition 1 Target Boundaries(3) = 1 2 3 Variable Potential Real Procedure "timestep" "timestep" End doesn't do anything so the module never gets called it should be something like Boundary Condition 1 Target Boundaries(3) = 1 2 3 Potential = Variable Time Real Procedure...
