Do you want to know how to add the FEM's of diferent parts into a sigle assembled FEM? If so you need to create an assembly from the parts who's FEM's you want to assemble and then you need to create a FE model and define the assembly FEM.

Nop.

I have an assembly fem already.

I went to "define connectors" on meshing to create a line connector which is suppossed to be used for welding.

But I can make it work. There is some "lengths" you have to specify, and everytime I "generate"the weld, it fails.

Help!
