I know Ole - I can ask him! :-)

Thank you, Michael.

My guessis that he used 1 unit by I unit square element. But ask him for confirmation.

Please, ask him also  these clarification:

- What is the material density he had in mind?

- What units did he assumed for force and elasticity in the code?

Hi again, Samuel - perhaps you can simply ask him yourself?

His e-mail address is

[email protected]

If you say hi from me and tell him that I asked you to e-mail him, then that might help a bit. :-) 

 Thank you, Professor Michael.
