[CIG-MC] Hi,some doubt about node_assemble

[Shijie Zhong]

Ting,

Element by element assembly is less efficient, although it is probably more general. Element by element assembly is not used as often in practice. We mostly use node assembly option.

Subject: [CIG-MC] Hi,some doubt about node_assemble

Hi,all,
    I'm now reading the program of citcom.There is one doubt about the parameter node_assemble.
In Element_calculations.c,  Au(stiffness matrix multiply velocity) will be calculated node by node or element by element depending whether node_assemble is set on.
But I cannot understand the advantages and disadvantages of each respect to the other.
Can you describe to me briefly in what situation node_assemble should be turned on?

Best wishes!
