The error "Out of memory during assembly" occurs.
This error message indicates that your computer does not have enough RAM memory to assemble the numerical model which you are working with. There are two distinct, sequential, memory-intensive steps that occur when you compute the solution:
Assembly: During assembly, the software takes the information about the model, the mesh, the physics (material properties, boundary conditions, etc.) and assembles a large system of equations.
Solving: During the solving step, the software solves the set of equations that has been assembled. This step will almost always require more memory than the assembly step.
If you run out of memory during the assembly step, you do not have enough RAM memory in your computer to solve your model. Follow the guidance given in Knowledge Base 1030
